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.

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

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

Everything you want is on the other side of fear

Procrastination is the thief of time and the enemy of success.

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. 

Dreams don't work unless you do.

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

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

Skills are built not born.

It is never too late to turn an unproductive day into a productive one.

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

Run in the morning before your body figures out what you're doing

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