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

Everything that happens was once a dream.

It always seems impossible until it's done.

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

If you want to succeed, double your failure rate.

The easiest person to deceive is yourself.

Never let a dark chapter make you forget that better days are ahead of you. Your story is far from over.

Failure is not the opposite of success, it is part of the success.

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. 

Start, struggle, fail, fix and learn. Repeat.

I think, therefore I am.

The wise person knows that no answer is also an answer

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

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

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