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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

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

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

I think, therefore I am.

Fall down seven times, stand up eight.

Everything you want is on the other side of fear

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

Failure to prepare = preparing to fail

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

You can be shown the path, but only you can make the first step.

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

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