Raising fees…..should I?

I am thinking of raising my fees. I have been told I could and should charge more. A part of me wants to make more money….but really, a bit more money will not make that much difference…so is the price increase an ego thing? or match what others do sort of thing? My husband says….NO, don’t fix something that is not broken. You have a good thing going….so there is some fear of losing current clients as well as not closing on new clients….I think my thoughts on this are key….what is my worth? why do I want/need to increase the fees? any guidance or thoughts to help me work through this?
