Paul said to bring your thoughts into captivity.
Alexander Graham Bell focus our pursuit of thoughts:

“Concentrate all your thoughts upon the work at hand.
The sun’s rays do not burn until brought to a focus.”

Norman Vincent Peale tells us that we will change our world when we change our thoughts.

“The happiness of your life depends upon the quality of your thoughts: therefore, guard accordingly, and take care that you entertain no notions unsuitable to virtue and reasonable nature.” ~Marcus Aurelius

If you but pause, think, and consider where your mind is powerful producing results internally, you should consider your production. Do they match?

Are you a thinker, or a do’er?
What will the results show
Of how you choose to think
About your life.

A Do’er is wasting effort
When no thought develops your plan
Don’t be a involved in doing
Until you’ve thought it through.
