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

Your attitude is everything. Pick a good one.

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

If you want to succeed, double your failure rate.

Lose an hour in the morning and you will spend all day looking for it.

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

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

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

Nobody said it’d be easy, they just promised it would be worth it.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

Life is full of opportunities. With every opportunity that is missed, another one is born.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

The power of reflection is the most powerful skill you’ll learn.

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.
