Sigh - I actually do it to myself sometimes. Someone will give me a compliment, and I'm so used to that "but" being put in there that I'll respond with a "thanks, but..." Trying to break that habit. I had a friend point it out to me at a competition where I did well, and she complimented me, and I replied with "thanks, but I should have done..." She glared at me and told me to stop stealing my own joy. It was the smack to the back of the head that I needed. Ever since then, at least in that environment, any compliment gets received with "thanks, it felt awesome!" Still working on it in other circumstances...sometimes I don't generalize well!
