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

The bad news is time flies, the good new is that you're the pilot.

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

The wise person knows that no answer is also an answer

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

Everything that happens was once a dream.

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. 

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

Don’t be afraid to work hard and find out how good you can really be.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

Success can never happen without the journey (struggle).

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

Shoot for the moon and even if you miss you’ll land among the stars/

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.
