self confidence goal

This is the only New Year resolution I've decided to make this year. I feel that this is a big problem in my life, I don't really have any and you need this to have any kind of healthy relationship, family friends, work. I am promising to if needed force myself to get out there and do things that will increase my self confidence and esteem. I would love any input on way to help proceed with I feel is going to be one of hardest things, I've ever done in my life, as this has been a issue for as long as I remember.  Thank in advance.Diana
