What should be the goal of our life ? Happiness? love? self accomplishment ? career ? wealth ?
The answer depends of course of our own personality. The word "personality" does not only mean what we are now but also what we have been before that made us what we are now. If while one was a kid, he did not have enough love or money, he might be craving for money or love in his adulthood. And he might definitely do everything to become the opposite of what he was as a kid.
Let's get personal and talk about what I think is the goal of my life: I want to be able to face myself everyday in the mirror and be fine with what I see. I think the word "happiness" is bullshit as you put everything and nothing under it. What is it to be happy ? Is it to smile everyday ? to feel ok with yourself, no matter what happens around you (starvation, wars, conflicts, rapes) ? That's very selfish. And how would you reach this happiness ? By having a job with a great salary ? somebody to sleep by your side ? kids to raise ? I leave it to the others !
I would rather stick to myself and make my mind on what my life should look like. Once I decide the way, I just have to follow the path... easy :-)
I think some of us will do little things in their little lives, others will do great thinks in their great lives. I do not pretend to be part of the latest but I will definitely not be within the first either. It does not matter to me what people expect or dream of. I just want to have the life I decide to have, no matter the cost of it. I will learn the lessons on the way, to become stronger and to go further. And if at 80 years' old I can look at myself in the mirror and not regret any single decision I took in the past 80 years, I guess I will be happy ! This is my goal of life...

Carpe Diem !
Don't waste time looking for things to come. But don't be afraid of your past; it is only the future who did not last. Remember to enjoy every single second of this life as in your next , you might have to handle harder situations...
