I've realized recently, that if I want to accomplish something, the best way to do that is to just do it.

Don't think about it too hard, don't do too much research in an attempt to get it all right the first time.  And most of all don't get so anxious in thinking about it, that you decide not to do it at all.

Just relax and give it a try.  You can perfect your technique later.  Once you try, you can see where you're lacking, and your fixes will be much more applicable.
