How can I feel like I have control over my life?

Haha that exact same thing happens to me. One time I wrote an essay on Huckleberry FInn and I thought it sucked but my teacher thought it was amazing and googled like half of it to make sure I didn't cheat XD Life is kind of funny that way. The thing about life is that it's not efficient at all.You never get out nearly as much as you put in. That being said I gave up control of my life. It seems like I am the biggest obstacle my life has ever had. If I just trust in God and go with the flow, things always turn out ok, and that problem you mentioned of walking randomly into success turns into a positive event.
