If you can understand just one thing thoroughly, then you will understand everything.

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

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

Go as far as you can see, when you get there, you’ll be able to see further

Do what you have always done and you will always be what you have always been

Success can never happen without the journey (struggle).

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

Everything you want is on the other side of fear

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

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

Mistakes have the power to turn you into something better than you were before.

It is never too late to turn an unproductive day into a productive one.

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

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

We all make mistakes. What matters is how we choose to move forwards from them.
