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

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

Failure to prepare = preparing to fail

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

Don't fear failure, fear being in the same exact same place next year as you are now.

It doesn’t matter where you start, it matters how you end

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

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

Pure mathematics is in its way, the poetry of logical ideas.

Success is not final, failure is not fatal.  It is the courage to continue that counts.

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

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Skills are built not born.

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