Steve Wozniak

You can make something big when young that will carry you through life. Look at all the big startups like Microsoft, Apple, Google, Facebook, Twitter, etc. They were all started by very young people who stumbled on something of unseen value. You'll know it when you hit a home run.

I love math and was a math teacher for many years, so it was fun for me to write several math books, including 'Fraction Fun,' 'Calculator Riddles,' and 'Shape Up!' 'Fun with Triangles and Other Polygons.'
