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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Everything you want is on the other side of fear

I think, therefore I am.

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

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

If you can understand just one thing thoroughly, then you will understand everything.

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

Hard work - a two way street where you get exactly what you put in.

The wise person knows that no answer is also an answer

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.

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

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. 

Skills are built not born.

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