This is probably not something I should talk too much about on a venue filled with potential employers or coworkers. But I think self-awareness is important, so I'll say a few things.
You're right on with the confidence (and persistence?) issues. That's one reason for doing the SC thing. It's helping me build up some confidence. I've been programming for quite a number of years. My day jobs for the last several years have destroyed the confidence I used to have. I'm getting it back, and quickly. And that makes me very, very happy.
OSS is something I want to be a core part of my job, because I use and appreciate it so much. I've tried getting involved with several projects before. Invariably my confidence falters enough that I give up before I really get going.
I'll go over to the two jobs threads from the other day and apply to some places. There were at least 3 or 4 that I would LOVE to work at.
