I get a bit awkward socially after a focused stretch of coding. Some days I'll go 4-6 hours only speaking to one person (a barista) briefly to order some coffee.

The next conversation I have after the coding stretch usually finds me struggling to make my mouth say the thoughts in my head, and then once it does, the sentence structure I use includes more nested clauses than usual.

But even after a 12 hour day of coding I rarely feel fatigued when it comes to learning something new about a technical area I'm studying, though admittedly I don't always spend my spare time working on those things.

I generally get very focused and periodically hours will go by and I won't realize what time it is, only to realize that it's hours later than I had thought. This is a double-edged sword. The flow state is amazing, but sometimes I wonder what happened to the day, even though it was a pleasant day.

I'm about half introvert, half extravert, but for me the most fatiguing thing is being in meetings that seem to last too long relative to their yield. I end up drained and need to recharge for a bit afterwords alone before I'm ready to do anything.
