To be quite honest, I've gotten better about me saying no. Over the past few years, I've moved from being a little too submissive about most things, to where I mostly will not agree to do something if I don't either trust or really know a person. But, if you know me well, it's hard to say no to you guys XD
I really do have a hard time saying no, mainly because I really don't want to be a jerk to anyone. However, recently I've been learning how to say no more often because I get tired of others taking advantage of me from time to time.
