I've studied successful people for over forty years and
I've found they are all alike in one way: the way they think.
- John C. Maxwell
That quote is from his book How Successful People Think and right of the gate, in the introduction, John address WHY CHANGE YOUR THINKING?
No doubt John's studied, or at least pondered, the unsuccessful and knew he needed to address so quickly why one would want to change their thinking.
It's simple really. If you don't like something in your life, anything; work, home, family, play. If you don't like it, if you want to improve, you must change your thinking. Of course, we're talking about IMPROVEMENT. You can not like your life and change your thinking to like it, to settle, but that's easy.
The hard part is changing your thinking to overcome a problem, overcome a situation, overcome where you are right now. But you are where you are, I am where I am, WE are were we are because of the journey we've been on, the paths we've taken, the decisions we've made, the happenings that have happened. We could not be where we are without ALL OF THAT.
And we can't get to a new place with the same thinking that got us HERE. And whether HERE is GREAT or horrible, it will take NEW THINKING to get to a new place.
