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

A hero is no braver than an ordinary man, but he is braver five minutes longer.

I think, therefore I am.

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

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. 

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

Tough times never last, but tough people do.

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

You can hire a tutor but you can't hire someone to practice for you.

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

Everything you want is on the other side of fear

Success is the sum of small repeated efforts, day in and day out.

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

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

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