Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

I think, therefore I am.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Skills are built not born.

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

I can is 100 times more important than IQ.

There are no shortcuts to any place worth going.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

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

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

Tomorrow is worth more than yesterday but less than today.

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

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

The road to success is like a staircase. If you want to succeed, double your failure rate
