I haven't been great at GAL, but I did really start getting pretty good at it before W decided she wanted to give it another shot.
What I think you want to do is three things:
- have fun - be unavailable - meet new people
Every activity doesn't have to hit all three. For instance, sometimes I just get cleaned up nice and go for coffee with a book. W doesn't know what I'm doing, only that I look good, smell good, and am gone. There's a "mystery" factor there, and yet, I'm doing something I enjoy, and am pretty chatty/smiley while gone.
Sometimes I go to happy hour, have a beer or two, and then go to a movie....all by myself. Sometimes I take one of the kids with me for some 1 on 1 time. Sometimes I go for a run with a group (love the hash runs...~$5 and a blast of a time). I work out most days at home as well, but afterwards, I usually find something to do, even if only for an hour or two. Just get out, be friendly, smile, and if at all possible, meet some people.
