Jim, I've been going on about this in lcause's thread, but I highly recommend skydiving!
Riding in a glider (the engine-less plane pulled by another plane and then let go) is also awesome!
Another one I like is going out to eat by myself. This may not be for everyone, but it helps me realize I'll be fine by myself, and I don't need anyone to feel comfortable in my own skin.
I do work out, but for me it feels kind of mindless. It helps me physically, but doesn't give me the mental boost that some people seem to get.
Someone else on here has done flotation therapy in a isolation tank, and that's something I'm thinking about doing.
For me, the point of GAL is not so much to "seem interesting" to the WAS, but to find the things I really enjoy and do them.
