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

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

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. 

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

The greatest enemy to human potential is your comfort zone

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

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

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.

99% of failures come from people who have the habit of making excuses.

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

Everything that happens was once a dream.

The bad news is time flies, the good new is that you're the pilot.

Procrastination makes easy things hard and hard things harder.
