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

Failure to prepare = preparing to fail

Don’t be afraid to work hard and find out how good you can really be.

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.

I have not failed, I've just found 10,000 ways that won't work.

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

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

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

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. 

He who has begun his task is half-way done. Have the courage to begin!

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

No one starts out on top. You have to work your way up.

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

The greatest mistake we make is living in constant fear that we will make one.

In order to become better than anybody else you must first become better than yourself.
