There are no bad mistakes in maths, only discoveries.

Procrastination makes easy things hard and hard things harder.

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

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

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

We learn more from failure than we do from success.

The wise person knows that no answer is also an answer

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

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

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. 

Success is not final, failure is not fatal.  It is the courage to continue that counts.

The temptation to quit will be the greatest when you are about to succeed

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

Your attitude is everything. Pick a good one.

The journey of a thousand miles begins with one step.
