We learn more from failure than we do from success.

We all have two lives. The second begins when we realise we only have one. 

The easiest person to deceive is yourself.

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

It always seems impossible until it's done.

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

Your limitation - its only your imagination.

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

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. 

Don’t practice until you get it right, practice until you can’t get it wrong.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

If you can understand just one thing thoroughly, then you will understand everything.

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

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

Procrastination makes easy things hard and hard things harder.
