Failure is NOT your destiny. Failure is the key to success.

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

You cannot start the next chapter of your life if you keep re-reading the last one.

Don't fear failure, fear being in the same exact same place next year as you are now.

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

You can have results or excuses, not both
