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

It always seems impossible until it's done.

There are no shortcuts to any place worth going.

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

You can be shown the path, but only you can make the first step.

If you want to succeed, double your failure rate.

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

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. 

I can is 100 times more important than IQ.

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

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

Success is a journey, not a destination.

Fall down seven times, stand up eight.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

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