I currently work in the oil field and also run my own business that specializes in custom web, and software development. I'm always trying to expand my business, but the oilfield takes up most of my time, what little time I have I try to spend with my family.
I love to learn and everything I know comes from reading tutorials online, or watching videos. I've decided that one of the best ways I can really embed what I learn is to create tutorials of my own based on the knowledge I obtain. What I really want to do, is take the written tutorials I find and make video versions of them, but having the time is another story.
For now it's just plain text tutorials. Once I get my business going and start having a little more time, I'll go back and convert them to video, or that's the plan anyway.
