You cannot escape the responsibility of tomorrow by evading it today

The greatest enemy to human potential is your comfort zone

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

The journey of a thousand miles begins with one step.

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.

Instead of finding reasons why you can't, find reasons why you can.

It always seems impossible until it's done.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Failure is not the opposite of success, it is part of the success.

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

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

Run in the morning before your body figures out what you're doing

Success can never happen without the journey (struggle).
