Wishful Thinking

I had an interview today. I believe the interview went well. I really want this new position. Finally, it's a position in my area of interest. Of course, I'm doubting myself and feeling I won't get the position. Everyone is telling me to think positive and I'm trying my damnedest to think positive. However, I just feel that I won't get it because it's too good to be true. I want to pray about it, but I feel guilty about praying for anything that suits only my best interests...is that wrong?? Oh well, I'm just going do my best with thinking positive.
