"The quality of your life depends upon the focus of your attention."
While conducting leadership training I invariably state this original (I think...) quote.
Why?
Renewal of your mind brings transformation. It doesn't happen any other way.
You may think a change of circumstance will bring improvement.
You may think your environment is keeping you down.
You may think the people around you are causing you to be stuck.
All these things matter, but the only way to change your circumstance is to Change your Mind.
This mind change produces transformation in you, which will lead to a change in your circumstance, environment, and the people that gather around you.
Refocus your attention on what is true, honorable, just, pure, lovely and commendable.
You will experience renewal, transformation, and peace.
