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

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

The master has failed more times than the beginner has even tried

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

If you fail, next time fail better.

We are all maths people : step 1 - do maths and step 2 - be a person. 

There are no bad mistakes in maths, only discoveries.

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.

Failure to prepare = preparing to fail

The easiest person to deceive is yourself.

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

Success is the sum of small repeated efforts, day in and day out.

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

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.
