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

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

Success can never happen without the journey (struggle).

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

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

Failure to prepare = preparing to fail

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

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

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

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

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

It is never too late to become what you might have been

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.
