The airport/hotel stuff is part of the job. I purposely take a day out of my travels though to sight-see, even if the organizers and/or my employer would rather I be at the event every single day networking. This is me caring for my mental health and recharging. I'm an ambivert and I can't go full throttle all the time.

On the note about getting sleep. I make sure I have 8 hours set aside for sleep, and 2 hours set aside for exercise every day. Nothing takes priority over that. Interestingly though, I've read some sleep studies where the scientists have discovered that our brains tend to stay in a more wakeful state when we're in unfamiliar surroundings. Even though I may sleep for 8 hours, I feel like I slept maybe 5 or 6.

IRT coding knowledge, it's definitely slipped, but I'm building on other skills now - it used to take me a week to craft a blog post, I can now do it in a day or two. Presentations would take me weeks to create, I can build a decent one in about a week.
