I feel blessed that I like my current job. Good manager, interesting work, limited amounts of bureaucracy. Most of this is a lucky coincidence but there are some things we can do. I had to explain many times to people which tasks I'm good at and which ones they should ask other people to do. I regularly defend this position. I set aside the morning for creative work only, no meetings, no admin, just thinking and solving. In the afternoon I down tools and do something physical, outside in daylight. A regular sleep cycle is absolutely critical for the maintenance of health and mood. Fresh food and companionship. Regular meditation. Do the basics well. These are the things that have made me happy.
