Just in short, I want to say that it really does work when you think positively.
I've been doing these positive thinking meditations every morning when I wake up, and everyday that I do them, I feel a lot better.
Yesterday, I told myself that I am going to have a good day and nothing is going to change it. I was right, I ran 16 laps on the track and I got all of my homework complete (I am now ahead of the game). I also attracted the attention of a few guys (I like it when that happens... it makes me happy lol), and I behaved myself and didn't eat any fatty foods. So word to the wise from the newly wise (aka me), think positively, and your life will be much better.
