mind testing

One of the projects this semester was to select a mind strengthener and report the effects. I selected to hang all of the posters and paintings upsidedown in my room. Supposedly this was going to strengthen my brain power. I have had my things upsidedown for over a month now and although at first I attempted to focus on them more, I have actually just ignored most of my posters the past few weeks. I have, however, noticed one painting quite a bit and have realized that it could have been painted either way. I guess this simple focus factor is actually a brain exersize in itself.
