Never underestimate the importance of small steps. small steps = big changes. 

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

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

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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. 

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

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.

It doesn’t matter where you start, it matters how you end

The journey of a thousand miles begins with one step.

I can is 100 times more important than IQ.

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

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

You cannot escape the responsibility of tomorrow by evading it today

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