Hello Glenn.
Excellent attitude. I really hope it works out for you and the Gigging Glenn becomes a reality. Try to play with others, even if they are better than you - this need not necessarily be in a gigging environment. You'll pick up examples of when to sit back and when to play harder; when to let the music breathe, etc. The more you become involved, the easier it will be to get that band together - maybe even well-before you retire.
Best
