I need a routine

I have yet to exercise, yet I manage to do a little dance or two.  Needless to say, I am not a good dancer.  Well, I cannot say that because I am just too shy to dance.  I am just shy period.  It doesn't seem that way because I am being so blunt.  I just don't know where to begin.  I am happy that I have lost the weight that I have.  I feel good about the weight that I have lost due to eating, but I have to step up my routine.  Well, that is if I have a routine which I don't have yet.  I am in need of wisdom and guidance and support in this.
