There are a lot of kind of people in the world. With regard to life fulfillment (in the sense of &quot;doing good things&quot;), I think there are two broad categories: people who require their work to be personally fulfilling or who require life outside of work to be so.<p>From personal experience, if you&#x27;re the kind of person who tends to be more invested at work (seeks out challenges, takes pride in your work, feels pleasure at a job well done), I&#x27;d hazard you might not be happy doing work you don&#x27;t find at least somewhat fulfilling.<p>My thought process being that personal_investment_in_work + fulfillment_only_outside_of_work = eventually resenting time spent at work as unfulfilling.<p>Everyone can&#x27;t work on cancer-curing, economy-stabilizing, poverty-eliminating, food-scarcity-solving, gender-equalizing, minority-protecting, free-speech-supporting things.<p>But we can at least move a little closer to working on something about which we can honestly say &quot;Yeah, that does make the world a slightly better place.&quot;
