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

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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

We learn more from failure than we do from success.

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

It always seems impossible until it's done.

Don’t hang your targets after you’re done shooting.

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

I think, therefore I am.

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. 

Failure is not the opposite of success, it is part of the success.

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

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

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

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