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

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

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

Don’t practice until you get it right, practice until you can’t get it wrong.

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

You cannot escape the responsibility of tomorrow by evading it today

Hope might be a good breakfast, but it makes a very poor dinner

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

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'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

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

It always seems impossible until it's done.

There is no elevator to success, you have to take the stairs.

Success is a journey, not a destination.

No one starts out on top. You have to work your way up.
