Aim at the sun and you may not reach it;
but your arrow will fly far higher
than if you had aimed at an object on a level with yourself.
Concentrate all your thoughts upon the work at hand.
The sun's rays do not burn until brought to a focus.
Alexander Graham Bell
If you focus on results, you will never change.
If you focus on change, you will get results
All that we are is the result of what we have thought.
Ray Knight: Focus Quotes
Concentration is the ability to think about absolutely nothing
when it is absolutely necessary.
Concentration is the secret of strength.
Ralph Waldo Emerson
You can't depend on your judgment
when your imagination is out of focus.
