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

It is never too late to become what you might have been

Don't fear failure, fear being in the same exact same place next year as you are now.

If you want to succeed, double your failure rate.

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

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.

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

Practice like you’ve never won. Perform like you’ve never lost.

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

Failure to prepare = preparing to fail

Failure is NOT your destiny. Failure is the key to success.

Tomorrow is worth more than yesterday but less than today.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

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

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