Sometimes it makes it hard to contribute back to the community, even though that same community makes my employment possible, because I fear that once they learn my tricks, the magic will be gone and I'll be seen as someone who merely pulled a fast one.
I've decided that this will be the year that I really work on some introspection and posting some of that knowledge. It will either help me get over my fear, or prove that I didn't know that much after all. At least I'll know.
