Philosophically speaking: The reason One will live another day; is, because that One did not die the day before.
The reason that One will get up everyday, educate Oneself, and try to earn a living; is, because, that One doesn't desire to die broke and stupid.
The only point of life is, that you are here.
The only meaning is, that, you are here.
The only reason is, that, you are here.
And, the only purpose of life, for you, is, that you are here.
Your 'task' is too do the best you can for your benefit, and for the benefit of all within your influence, while you are here.
The signs are everywhere too remind you of this; especially on the Mall Directory.
