Nothing wrong with being a "yes man" if by "yes man" you mean someone who does what they are told and goes out of their way to help others. I don't want to preach selfishness, I want to preach self-sufficiency - in that it's your life, and if it isn't making you happy you need to evaluate if it's helping other people as much as it's hurting you. It sounds like you're already finding limits in what you're doing professionally. Time to find your limits in what you're doing personally. Believe in yourself yadda yadda yadda but also recognize that you gotta look out for you because nobody else is (unless you're married or in a close relationship with someone - the best thing about a real relationship like that is you support each others' dreams). It's gonna work out, man. Step one is waking up and going "something's not quite right." That realization is halfway to remedy. Good luck.
