Throwing Away Bad Thoughts

From Readers' Digest:

"Treat negative thoughts like old newspaper at the bottom of the birdcage. When students were asked to write bad thoughts about their body and then toss the paper in a garbage can, they were later more positive about their body image than those who hadn't discarded them. When they tucked positive thoughts about a healthy diet into their pocket, they were more likely to want to follow that diet later than those who threw such thoughts away. How you treat your thoughts affects behavior."
