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

I can is 100 times more important than IQ.

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

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

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

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

We learn more from failure than we do from success.

There are no bad mistakes in maths, only discoveries.

Tough times never last, but tough people do.

There are no shortcuts to any place worth going.

Procrastination makes easy things hard and hard things harder.

Just stick with it, what seems hard now will one day be your warm up.

The greatest mistake we make is living in constant fear that we will make one.

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

Knowledge is of no value unless you put it into practice.
