Honestly, the main thing was to start treating my life as an experiment. Before that, I was just doing what the doctors told me without checking to see if their recommendations actually produced good results. For me, experimenting mainly meant that I 1. tried tracking a bunch of things on my own and analyzing the results, and 2. was willing to try a lot more things, like caffeine pills and antidepressants, because the information value was high. (I first did my research and, when relevant, checked with a doctor, of course.) I think there was a mindset shift somewhere along the way explicitly rejecting that the status quo was innately good. If I was unsatisfied with something, I could try to change it, and I was effective if it got better. After I started experimenting, I prioritized experiments to deal with the bottleneck of fatigue and it was fairly straightforward.
