What Do You Think?

I recently heard the average person has over 600,000 thoughts a day, and the vast majority of these−over 75%--are negative. Do you think this is true? It got me thinking about my own self-talk. Do I do this? If so, in what ways? I decided to take a week and evaluate my thought life. If the majority of my thoughts are negative, then replacing them with positive ones should improve my attitude and brighten my days. I'll keep you posted (this is the accountability part).
