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

The wise person knows that no answer is also an answer

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

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

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

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

Success is a journey, not a destination.

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

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

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.
