There are no shortcuts to any place worth going.

We learn more from failure than we do from success.

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

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

Time is your friend, impulse is your enemy.

You cannot escape the responsibility of tomorrow by evading it today

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 master has failed more times than the beginner has even tried

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

Failure to prepare = preparing to fail

Fall down seven times, stand up eight.

You're not in competition with anyone but yourself. Outdo your past, not other people.

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

99% of genius comes from hard work, the remaining 1% comes from innate talent

Failure is not the opposite of success, it is part of the success.
