The road to success is like a staircase. If you want to succeed, double your failure rate

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

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. 

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

Skills are built not born.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Lose an hour in the morning and you will spend all day looking for it.

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

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

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

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

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

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

Everything that happens was once a dream.

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