Just basically needed to remind myself about a few things:
1) Next year when you attend Gallifrey One, actually introduce yourself to people, especially people you follow on DeviantArt/Tumblr/Twitter. You are not a shy person, you just worry entirely too much that you are somehow bothering someone by saying hello and how much you like their work. Stop it.
2) For crissakes, scan some of your art and post it here, or find some photos of costumes you've made so that people can begin to associate you with something... anything! Why are you hanging out on an art site without sharing any of your art?
3) Get beyond the planning stages and actually make (and wear!) some cosplay outfits! You are a really good stitcher (you used to get paid to do it, dork) and you have no good reason to use the excuse "but if I lose a lot of weight, the costume won't fit me anymore" because YOU KNOW HOW TO ALTER CLOTHING, you twit. No more waffling.
4) As your friend Karen says, "do a favor for your future self." Stop dawdling and get to it!
