“We become what we think about.”

Earl Nightingale

I think it depends on the person’s perspective. I mean it can only apply to those who are determined and motivated to act on what they think about instead of just thinking about it and not acting upon it. For example many people have a new year’s resolution that they want to lose weight but I know for a fact only have of those who act upon it go through with the resolution while others just give up. But those who are motivated to act on what they think about they can become successful because they always go through with what it is they are thinking about.
