I'm immediately put in mind of a Charlie Brown cartoon, when he's looking at a huge set of books with a long face. Marcie comes by and asks him "Why the long face?" His reply is "The more I learn, the more I know what I don't know."

I've always been amazed and heartened at the fact that there's so much about programming (and life!) that I don't know ... that I'll never know. If I knew everything, then life would just be boring! The joy is in the learning, not the knowing.

I commend you on the capability for self-reflection and the strength of character to know (and work to fix) where you're lacking. It's something that I know I have to re-learn every day (and for which I thank my fiancee for having the patience to handle!).

We are the carpenters and bricklayers of the Information Age.

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
