Courage

When I was growing up, I had independent thoughts about some events or phenomenon, which made me feel angry or irritable. I was unsatisfied with my present situation for a long time. However, I always dreamt that some day some other people could change it before, though I denied change from myself. Now I realized that it's wrong, that no one can help me if I don't to it by myself. I need some courage to make some change.

[Good work.  Remember that 'it's' means "it is", while 'its' is the possessive of it.  It's an easy mistake to make.]
