Drudgery is not as much drudgery when there is variety. I think a lot of people who see their work as "drudgery" actually just are forced to do one thing and never even think about doing a second thing during their day.
Take making software I felt was making the world better versus software that was not. When I knew my work dramatically improved the lives of tens/hundreds of thousands of people and by extensions their families touched hundreds of thousands more versus just a software job in a kind of bad industry. The positive job it was easy to put in ridiculous hours. For the other straight 9-5 felt like too long.
