I had a similar realization, I suppose when I was 17 or so. I realized that I was quite a negative person, and tried to become more aware of how I presented myself to other people. While this stragety worked in the eyes of others, I was still the same in my mind. The negative thoughts and criticism were merely kept to myself.
This is a nice reminder of something I really need to be more aware of. Thanks!
(By the way, I'm sort of trying out the raw foods thing, but I'm having a hard time finding anything to eat other than fruits and salad. Do you have any tips to share with those new to the idea, such as myself?)
