Your attitude is everything. Pick a good one.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

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

The easiest person to deceive is yourself.

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

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

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

Hope might be a good breakfast, but it makes a very poor dinner

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

Knowledge is of no value unless you put it into practice.

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. 

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

Tomorrow is worth more than yesterday but less than today.

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

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