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

The greatest mistake we make is living in constant fear that we will make one.

He who has begun his task is half-way done. Have the courage to begin!

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

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

It is never too late to become what you might have been

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

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

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

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

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. 

The journey of a thousand miles begins with one step.

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

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

Skills are built not born.
