That is what I do. I look at products and think about them for a while then decide I don't need them and move onto the next product until I find something I'm interested in. I will look at watches, t-shirts, games and gadgets. Pocket projectors, books, wall clocks.
The other thing to do is stand about outside and breathe in some nice fresh air. Thank God for fresh air every morning and evening. Nice cool fresh air and the ability to stop thinking about stuff for a while.
Keep those little happy thoughts coming.
