Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

It always seems impossible until it's done.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

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

There are no shortcuts to any place worth going.

There is no elevator to success, you have to take the stairs.

Shoot for the moon and even if you miss you’ll land among the stars/

We learn more from failure than we do from success.

The greatest enemy to human potential is your comfort zone

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

Everything you want is on the other side of fear

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

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. 

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.
