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

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

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

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

The journey of a thousand miles begins with one step. 

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Your limitation - its only your imagination.

You cannot escape the responsibility of tomorrow by evading it today

Knowledge is of no value unless you put it into practice.

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

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. 

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

There are no shortcuts to any place worth going.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

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