I can totally relate to this. I experienced this after working steadily 4 years and then having a close friend pass unexpectedly. Suddenly everything I was spending all my time on felt like a waste of time. Now, almost two years later I'm doing better and even looking to work in a non-remote scenario. I think it's great to be on the lookout for signs of burnout, but on the other hand it's equally important to use our time wisely and do the things we love.
