It is never too late to turn an unproductive day into a productive one.

The greatest enemy to human potential is your comfort zone

Tomorrow is worth more than yesterday but less than today.

Practice like you’ve never won. Perform like you’ve never lost.

You can have results or excuses, not both

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

There are no bad mistakes in maths, only discoveries.

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

Just stick with it, what seems hard now will one day be your warm up.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Skills are built not born.

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.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

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

It always seems impossible until it's done.
