Saw a bumper sticker today that read:
"Don't believe everything you think"
Pretty powerful if you give it some thought. It seems like often we just assume that every thought that pops into our heads is actually true.
"Those people are talking about me."
"I look fat in this."
"I'll never lose this weight."
etc. etc. etc.......
Just because you think it doesn't mean it's true. Your own thought might be holding you back!
