Result of the Battle!

Does it take more energy to be positive, than it is to be negative? I don't know. I Googled that question this morning and came across Tiny Buddha, who tells me that the original Buddha said: "The mind is everything. What we think we become."

Is that true? I don't know. Who am I to disagree with the Buddha? Some times I feel my mind is like a battlefield. There are the positive thoughts and the negative thoughts and they battle it out. The battle itself is sort of tiring and defining. I suppose I am the result of the battle.
