FINISH THEM! Ask for help if you need it!
I started doing "web stuff" about 3 years ago and have learned sooo much just by forcing myself to do it.
It's so funny to me to see how much I've changed, I came across one of the first ever "apps" that I made a few days ago. It was a DVD cataloger that I made my Dad for his birthday (He glanced at it, went "huh", then bought some commercial version of the same thing...humph) and it was kindof cool to look over the shoulder of Ryan from 3 years ago to see what he was doing.
What's keeping you from finishing these things?
