Don’t hang your targets after you’re done shooting.

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

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

We learn more from failure than we do from success.

We all make mistakes. What matters is how we choose to move forwards from them.

The greatest enemy to human potential is your comfort zone

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

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.
