WhAt aBoUt LiFe?

Why can't people just live their lives alone by minding their own businesses?

All of us have encountered obstacles, but whenever i get tired of these non stop jitters about what's going to happen next, i just look back at better times, the glorious and happy chapter of my life when all that mattered to me were vacations, drinking escapades with friends, party and etc. but it feels bad that are lives are bounded with a lot of responsibilities and things were getting really hard for me especially when people your expecting to help you were not around in times of your need, that's why they say "you should never really expect other to e happy for you, as they are too busy protecting their own turf".
On the other hand, i realize that the true meaning of life is about fighting, trying, winning, losing but still standing proudly to show everyone your power and will to survive.
Sometimes we experience a life that is too terrible but there is no such life as that, maybe the reason why we see our life as this, is we don't really appreciate the good things happening to us, or we are just too focused on the bad things overpowering our will to be brave and hope for better tomorrow but i know that the time will come that we would be at last happy and we must thank God for a life full of trials because he made us a better person and i thanked him that in the darkess moment of my life, he brightens my mind.
