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

Lose an hour in the morning and you will spend all day looking for it.

It always seems impossible until it's done.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

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

The easiest person to deceive is yourself.

Never underestimate the importance of small steps. small steps = big changes. 

There are no bad mistakes in maths, only discoveries.

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

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

I have not failed, I've just found 10,000 ways that won't work.

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

Tomorrow is worth more than yesterday but less than today.
