Instead of finding reasons why you can't, find reasons why you can.

I think, therefore I am.

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

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

Tomorrow is worth more than yesterday but less than today.

We all make mistakes. What matters is how we choose to move forwards from them.

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. 

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Tough times never last, but tough people do.

Failure is NOT your destiny. Failure is the key to success.

The journey of a thousand miles begins with one step. 

It is never too late to turn an unproductive day into a productive one.

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

Lose an hour in the morning and you will spend all day looking for it.

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