Thoughts from the person with the least credibility in the field.
1) Don't conflate eustress, distress, or work.
2) Always something better to do, always have your needs basically met.
3) People's problems are never that complicated. Life isn't that complicated, really. What is complicated: people refusing to look at the big picture and accept basic life tenets. Anyone who has seen a lifetime movie knows that the road to happiness is not a middle aged guy divorcing his wife for a 20s beauty. Go tell that to anyone at the corvette dealership, see if they are willing to hear that.
4) With #3 in mind, never work harder than the patient.
5) Start with creating rigid personal boundaries related to work hours, doing unpaid work (including returning calls), etc.
6) Move onto boundaries related to external reminders. Would you like it, if your PCP was thinking about you while naked? Then maybe you shouldn't think about your patients when the bra comes off, or when you're in your boxers.
7) Use alternative boundaries to enforce personal boundaries. It would unethical to do work when you've had a couple drinks, so knock it off.
8) Create a mix of easy and complicated work. Crafting a mix of work that is neither boring nor overwhelming is one of the most important skills you can do.
9) If bored, innovate or evolve. Find new things to study, try to get suave in something you do routinely (e.g., getting a lamp next to a patient chair, putting marks on the lampshade that allows you to estimate pupil size and accommodation).
10) Get some therapy. Take a vacation.
