I don't know it all, but what I do know I love to share with anyone who will listen. I've spent the majority of my life teaching many subjects. At 14 I started teaching martial arts and got hooked. I taught college courses for about 5 years but felt held back by rules and regulations. So I decided to make my own tutorials. Here are my most popular ones with more to come.
If you have any questions or would like me to cover a certain topic contact me and I'd be happy to help you when I get the time.
