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

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

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

You cannot escape the responsibility of tomorrow by evading it today

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

The greatest enemy to human potential is your comfort zone

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

A book a day keeps the stupidity away.

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

Success is a journey, not a destination.

Success can never happen without the journey (struggle).

The master has failed more times than the beginner has even tried

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

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. 

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