My Own Worst Enemy

Life has been hectic, and lately I've been running around wondering exactly who I am and where I'm going. The poem below reflects a lot of that. It's going to have to suffice as an explaination of the matter, because I really don't feel like writing about it anymore.
All I'll say is that sometimes I'm my own worst enemy, and sometimes I quit because I don't think I can make a difference. And when I've quit something, I usually find out later that I shouldn't have.
I'm done writing now. Fill in the rest of the blanks yourself. Goodnight.
