A major stimulant to creative thinking is focused questions.

Your mind is like a garden - unless you cultivate flowers, weeds will flourish. To keep your mind positive, substitute positive thoughts for negative thoughts.

Treat objections as requests for further information.

Accept complete responsibility both for understanding and for being understood.

If you think a certain thought long enough and hard enough, it becomes a fixed belief and you will find yourself behaving on the outside in a manner consistent with it.

Destructive criticism is the biggest single enemy of human potential. It is worse than cancer or heart disease. While those diseases can ultimately lead to the deterioration and death of an individual, destructive criticism kills the soul of the person but leaves the body walking around.

Your ability to set and achieve goals is perhaps the most important skill you can ever develop.
