Why can't I just know everything?

Well, I surfed around this morning for a couple of hours to try and find some info on how to customize my blog. The only conclusion I have come to is: I don't know what the heck I am doing! The lazy side of me wants to give up and say forget it. My stubborn side wants to keep searching and find a way to do it myself. I'll probably end up going for the middle of the road approach and asking for help. I know what I want...I just don't know how to implement the idea. As with most things with me. I often come up with some really cool ideas, but don't know how to actually make them happen.
