The greatest enemy to human potential is your comfort zone

Don’t hang your targets after you’re done shooting.

Knowledge is of no value unless you put it into practice.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

It is never too late to turn an unproductive day into a productive one.

Don’t be afraid to work hard and find out how good you can really be.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Mistakes have the power to turn you into something better than you were before.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

The wise person knows that no answer is also an answer

A hero is no braver than an ordinary man, but he is braver five minutes longer.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

The master has failed more times than the beginner has even tried

He who has begun his task is half-way done. Have the courage to begin!

You can hire a tutor but you can't hire someone to practice for you.
