This relates to questions that come up when wanting and/or pursuing a life of variety:

It reminds me of some of the things I’ve thought about and struggled with over the years. Those struggles were part of how I came up with some of the ideas about being a variety person, and part of why I started this site!

I guess I’m more of the opinion that it’s better to have a certain amount of variety on a daily and weekly basis. Some of the people who responded to the Quora question suggest doing one thing for a number of years and then switching. I’ve done some of that too. But I wish I had been more OK with having more variety during those times. And I wish society was more set up to allow that, rather than generally channeling people to specialize.
