Opinions about life

Two different guys speak:

Why do I exist?Perhpas i never wanted to exist!I am like a molecule among people!I am nothing in this Earth just like a grain of sand...I would like to be known like stars on TV; i would like to seduce any girls in this world!Nobody can stop me!But Nobody doesn't give attention to me...I will commit suicide.

Now a happy man would think:

Why do I exist?To give pleasure to woman and to earn money:I like people who admires me!I hate people who are always unhapppy!i prefer not to talk with me because i will become like them sad and useless!I don't give them a shit!yeah i know,I seem selfish but every human being is selfish isn't it?

These are opinions of guys i have met. What can life bring to us?
