I’ve been delivering online synchronous training for over 10 years and working almost exclusively remote for the past 3 years.  So why am I so exhausted at the end of every work-from-home day for the past 11 months?  Other than my kids ALSO being home for the past 11 months, I can point to one other thing that is different - my webcam. Before last March, I didn’t even have a working external webcam.  But for the past 11 months, nearly every meeting and training session I’ve been a part of has utilized my camera.  And it’s wearing me out.
