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

Failure to prepare = preparing to fail

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

Mistakes have the power to turn you into something better than you were before.

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

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. 

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

Success can never happen without the journey (struggle).

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

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

Never underestimate the importance of small steps. small steps = big changes. 

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Nobody said it’d be easy, they just promised it would be worth it.

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

I can is 100 times more important than IQ.
