In the last post, I said that I started my journey as an instructor actually as a student. I used to take online courses every week. And even several at a time!
That inspired me to set aside 1 hour per day to watch some of the great training that I've purchased over the years. Not only do I enjoy learning, but I need to study good video content to help me become a better instructor.
I was going to watch that Daniel Negraneau Masterclass that I talked about, but it's still not fully available and I don't want to watch the videos out of order, so I decided to start a new class. I'm watching Canadian hero Chris Hadfield's Masterclass instead.
Chris Hadfield is an astronaut, and he's teaching space exploration online. How interesting is that! Very!
So anyways, how is what I do (online instructor) relate to what he does (astronaut)?
Chris says that the equation for drag is D = ½ρv2CdS. Well, I am not in a position to question him on that. Drag is the resistance the atmosphere pushes against a rocket taking off from Earth and is the main force you have to fight against besides gravity.
So a rocketship must fight a resisting force, but the higher it gets up above the Earth, the less drag it encounters. The rho, the density of the air around the ship, gets lower as you get higher up.
I contend that an instructor has resisting forces too when they are first starting out. When you are first starting, with feet planted on the ground, you have no audience, no following. You really need to push hard against the drag to get off the ground. The more people you have in your courses, the more followers you have, the more email addresses you've collected, then the air gets a bit thinner and drag starts to reduce.
But drag doesn't get to zero, and you still have to work hard to get higher. Eventually, you've built a nice recurring business, you're able to sell products without much drag, and the chances of you crashing back down to ground level become lower.
Now of course, I am not sure that there is the concept of a stable orbit. Once you've got your instructing business off the ground, and are making a nice income, and it is not difficult to keep that going, you still have to work hard to keep it. If you stop working, in a year, or two, your business will come crashing down and you'll be starting over.
Or maybe that is exactly like orbit. Don't space objects crash to Earth too once they run out of fuel? 🙂
