Never going back

Over the years I've found that I never go back. For example, when I left home for college I only returned for vacations. Instead I worked each summer at college or as a co-operative intern. At work, I've considered returning to a previous department, but somehow I like to do new things and have never returned to one. When I retire will I ever work again? So I don't know if I'll ever break this trend, but if I do then that'll be a new thing for me. Now is that going back or is that going forward?
