There's a pie chart in my mind, there's a large positive part and a small negative part of it, sometimes when my mind starts to wonder and think negatively the negative part of the pie chart tends to eat up the whole pie, and then i start to tell my self STOP! divert my thinking into happy and positive thoughts, then slowly i regain balance and control of my mind. when i tend to think negatively it's like there's no sol'n at all then if i think positively seems everything is possible. :D
