While I started my new job a few weeks ago, I banned myself from working on any side projects for a given period. It's unheard of for me to not be working on about five things at once, but I've been overstretched for the past while and in a cycle of energetic depletion, so this was a sensible step.
A week or so ago was the first time in a while where I felt very aware of having the surplus of time and energy to work on things. Usually, the mismatch is between my impulse to work on things and the available time and energy, so this was a good sign -- though I'll continue sitting on my hands for a while longer, as I want to actually feel like I have reserves of energy.
I realise also that what I'm doing partly is replicating my feeling around a longish holiday where I'm travelling -- something I did rarely before the pandemic, and haven't done at all since. While I'm all for relaxation and travel, I do find that, after about a week at most, I'm itching to have sit-down time at a desk to at least get all of the things out of my head. Returning to my office with that sort of energy -- where I'm desperate to get out the gate and moving -- has always been a good feeling when it's happened.
