I do have a small confession in that I did some language teaching many years ago. This is not my current subject.
I drank a fair amount back then and frequently taught with hangovers. I got away with it then as a young guy, but it’s not doable now nor is it sustainable.
The point here is so many more things are possible when alcohol is taken out the equation. All of us here are good at something, and not being slowed down by alcohol will help us get there.
