Success is not final, failure is not fatal.  It is the courage to continue that counts.

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

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

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

You're not in competition with anyone but yourself. Outdo your past, not other people.

Pure mathematics is in its way, the poetry of logical ideas.

Hard work beats talent when talent doesn't work hard.

It doesn’t matter where you start, it matters how you end

99% of genius comes from hard work, the remaining 1% comes from innate talent

The greatest enemy to human potential is your comfort zone

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

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 easiest person to deceive is yourself.

Hard work - a two way street where you get exactly what you put in.

There is no elevator to success, you have to take the stairs.
