Should I stop being so helpful?
I'm called 'post-it girl' because my colleagues just put a post it note on my desk on things or favors that they want done. This is my fault actually, because initially I'd say yes to every favor, even if it was a personal favor, and I would do it. Now, I don't even have to ask if they want anything, they have started to leave post it notes on my monitor for small favors like taking printouts or things like that. What should I do?
