The journey of a thousand miles begins with one step. 

Success can never happen without the journey (struggle).

The bad news is time flies, the good new is that you're the pilot.

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

Skills are built not born.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

I have not failed, I've just found 10,000 ways that won't work.

Everything you want is on the other side of fear

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

Tough times never last, but tough people do.

Failure to prepare = preparing to fail

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

The road to success is like a staircase. If you want to succeed, double your failure rate

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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.
