Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Everything that happens was once a dream.

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

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

Success can never happen without the journey (struggle).

If you can understand just one thing thoroughly, then you will understand everything.

99% of genius comes from hard work, the remaining 1% comes from innate talent

I can is 100 times more important than IQ.

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

The greatest enemy to human potential is your comfort zone

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

Try and do one thing each day that you would really rather not do.

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. 

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

Hard work beats talent when talent doesn't work hard.
