Seems like anything remotely interesting, will quickly not be interesting as a full time job. I try to get the highest paying, lowest brain power job that balances my time vs money. Ideally, I have enough money, and more time to stimulate my wandering interests beyond work. In other words, I have up on finding purpose and challenge at work. I have enough purpose and mental challenge in y day to day life. I want to be about to tolerate work without burning out.
