A hero is no braver than an ordinary man, but he is braver five minutes longer.

Success is the sum of small repeated efforts, day in and day out.

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

Failure to prepare = preparing to fail

Skills are built not born.

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. 

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

I think, therefore I am.

Patience is when you’re supposed to get mad, but you choose to understand

We learn more from failure than we do from success.

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