Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

Pure mathematics is in its way, the poetry of logical ideas.

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

Fall down seven times, stand up eight.

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

Everything that happens was once a dream.

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

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

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

Just stick with it, what seems hard now will one day be your warm up.

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. 

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

In order to become better than anybody else you must first become better than yourself.
