Since I tend to do too much thinking while reading or walking, I like to do something that requires a little concentration. Talking on the phone helps me a lot or hanging out with other people, etc. I think a lot when I am by myself so I try to hang out with others. Also, I go to school 2 nights a week.. and even though I have been able to maintain an A average (Go Me!!! Go Me!!!) I find that I have to put my CH out of my mind completely in order to study, etc.
Scrapbooking and cleaning and gardening and shopping (Not buying, just shopping.... YES, there is a difference) are my go to things, a lot.
