Try and do one thing each day that you would really rather not do.

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

Time is your friend, impulse is your enemy.

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

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

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.

No one starts out on top. You have to work your way up.

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

The road to success is like a staircase. If you want to succeed, double your failure rate

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Fall down seven times, stand up eight.

If you want to succeed, double your failure rate.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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.
