Allah almighty has bestowed upon us so many gifts that even if you try your hardest, you cannot count them all: 

He gave you all that you had asked Him. If you enumerate Allah’s blessings, you will not be able to count them. Indeed, man is most unfair and ungrateful! (Holy Quran, 14:34)

However, if you reflect further, you will realize that the greatest favor of Allah to us is the opportunity to use these gifts. Life is a priceless blessing that many people often overlook. We must appreciate this precious gift from Allah and use it in the best way possible. Regarding this, Allah Almighty warns us about wasting our time in the Holy Quran,

I swear by Time! * Mankind is indeed in loss, * except those who have faith and do righteous deeds, and enjoin one another to [follow] the truth, and enjoin one another to patience. (103:1-3) 

This life is short yet crucial because it’s all we have got. Allah almighty says,
On the Judgement Day, He will gather them [it will be] as if they had not remained [in the world] except for a moment of the day getting acquainted with one another. They are certainly losers who deny the encounter with Allah, and they are not guided. (10:45)

Imam Ali (AS) also states,

Your opportunities pass just like the clouds pass; therefore use the good opportunities. (1)

Those who wasted their time in this world on trivial matters will lament on the Judgement Day:

They are certainly losers who deny the encounter with Allah. When the Judgement Day overtakes them suddenly, they will say, ‘Alas for us, for what we wasted in the world!’ And they will bear their burdens on their backs. Look! Evil is what they bear! (6:31)

Giving the importance of time, Islam has set some principles to make the most efficient use of it

Avoid wasting time on unimportant things 

Many of the activities we engage in during the day are unproductive. In the Islamic view, it is crucial to understand the importance of spending time on beneficial things. Imam Sadiq (AS) says,
One of the signs of a good Muslim is that he avoids things that have nothing to do with him (2)

Self-Assessment

Imam Ali (AS) says:

It is so necessary for one to have a time during the day allocated for self-Assessment so that they could see what they have done during the day and the night that had benefit or damage for them. (3)

Imam Kazim (AS) advised his pupil Hisham:

O Hisham! He is not one of us who doesn’t assess himself every day. (4)

Set goals

Imam Ali (AS) said,

God bless the one … who sets goals. (5)

Time management

Imam Ali (AS) said,

For achieving success, manage your time, and to manage your time, think clearly, and for thinking clearly, hide your secrets. (6)

To effectively manage time the most important thing is to know how to allocate every part of our daily life for something needed. In this regard Imam Kazim (AS) says,

Try to divide your time into four parts: one for praying and talking to Allah, another for work, one for spending time with your friends and trustworthy individuals who let you know about your faults and imperfections and who sincerely love you. The last part is for your lawful pleasures and by this last part, you get ready for the other three parts. 

Don’t talk with yourself about poverty or length of lifetime. Because anyone who thinks about poverty will become miserly and anyone who thinks about the length of life will become greedy. Give yourself your share of this world by pleasing yourself with lawful things which don’t harm your character or waste your time. (7)

Think before acting

Imam Ali (AS) said:

Thinking before acting saves you from regretting. (8) 

One of the best ways to save time is to think carefully before taking any action. Some people think that acting impulsively leads to faster success. They think that overthinking is a sign of fear, so they advocate for thinking less and acting more. However, Islam doesn’t support this notion as it encourages thoughtful consideration and reflection before taking any action. 
In this regard, Imam Ali (AS) said,

Every movement requires knowledge. (9)

Imam Sadiq (AS) also said,

The one who acts without needed insight is like a passenger on the wrong road. The faster he goes, the farther he gets from his destination. (10)

The holy Prophet (PBUH & HP) said:

When you want to do something, think about its results, if it brings benefits or progress, act and if it is harmful or causes regression, refrain from doing it. (11) 

We only live this life once, but its consequences will remain in the Hereafter. Don’t squander this opportunity and by making the best of it, secure a better life for yourself in the Hereafter.

Perhaps one of the most important questions for each of us about life is what a good and flourishing life is and most generally if it is worth living.

Many people, including great philosophers and scholars of ethics and mysticism throughout history, have tried to find an answer to this question regarding life worth. Albert Camus, one of the famous authors and philosophers of the 20th century, tried hard to fulfill his lifelong quest to shed light on the meaning of our lives, such that he believed: “Judging whether life is or is not worth living amounts to answering the fundamental question of philosophy. All the rest […] comes afterward. Those are games; one must first answer this” [2]. 

Now let’s see how different people have answered this important question about life worth. We can divide these viewpoints into three categories:

"Life Is not Worth Living at All"

1. They believe life costs a lot and has very few benefits for us. As Woody Allan, the pessimist American director, puts: “Most of life is tragic. You're born, you don't know why. You're here, you don't know why. You go, you die. Your family dies. Your friends die. People suffer. People live in constant terror. The world is full of poverty and corruption and war and Nazis and tsunamis. The net result, the final count is, you lose - you don't beat the house” [3]. Or as Samuel Butler says: “life is one long process of getting tired” [4]. So some of these people think why not we commit suicide to get rid of this miserable life?!

"Life Worthes Living All the Time, No Matter What!"

2. These people believe life is so valuable no matter how it seems and we have to live it at any price. Lots of people choose to think this way. Henry James has said: “Be not afraid of life believe that life is worth living and your belief will create the fact” [5]. Or there is another quote from Ellen DeGeneres that says: “My life is perfect even when it's not” [6]. Also, one of the most popular contemporary writers, Paulo Coelho seems to have a kind of optimistic view about life when he says: “Never give up. When your heart becomes tired, just walk with your legs – but move on” [7]
Some other people seem to have found the golden mean between the two previous extremes:

Is Life Worth?

"Life Is not Completely Worthless, Neither Absolutely Valuable"

3. So, sometimes it is worth living and sometimes not. This is what Islam and Islamic leaders teach their followers about life worth. There are examples in the lives of the infallible Imams in which they indicate that we are not created only to live this worldly life and that this life is merely a path for us to reach a higher status. As the Holy Quran says: “while the Hereafter is better and more lasting” (87:17). So, we should always think if this earthly life will be to our benefit in the hereafter or not. If yes, then it is worth living; if not fight for those benefits even if you die. 

One of the most significant role models for us in this regard is Imam Hussain (AS), the third infallible Imam, whose act of sacrifice has left a profound impact on humankind throughout history. Imam Hussain (AS) believed accepting humiliation and obedience to mean people is like living in hell. So, when all he did to guide his enemies to the right path failed, he said: “To me, death is nothing but happiness, and living under tyrants nothing but living in a hell” [8].

At this state, death to him is more desirable than living under the oppression of the tyrants and surrendering to their wishes. Therefore, when he was placed in a dilemma by the oppressors to be humiliated by swearing allegiance to the tyrant of the time, Yazid, or to fight and probably die, he decided to fight even if he died. He sacrificed all he had in this way and departed this earthly life with glory. 
Now, after about 1400 years, every year in Muharram, lots of ceremonies are held around the world to commemorate the anniversary of his martyrdom. Lots of people from different religions get influenced by him and his ideology and sometimes it makes them embrace Islam.

Which point of view do you agree about life worth? Will you ever give up your benefits for the good of others to make them have a flourishing and more valuable life?
