YOu control your inner world by the way you think. Two ppl can have the same things happen in life and one could be happy while the would be miserable. You'll only looking at the bad. There is a balance of action and reaction and good and bad no matter how bad something is there good and vice versa. Denying the other end of the sectrum is like denying there is a night after the day. Change always have a good and bad side no matter how good or bad something may appear to be.
the meaning to life is to learn and to grow.
