The temptation to quit will be the greatest when you are about to succeed

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

You cannot escape the responsibility of tomorrow by evading it today

Dreams don't work unless you do.

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

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Just stick with it, what seems hard now will one day be your warm up.

Procrastination makes easy things hard and hard things harder.

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

Time is your friend, impulse is your enemy.

The greatest mistake we make is living in constant fear that we will make one.

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

Everything you want is on the other side of fear

The greatest enemy to human potential is your comfort zone

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