Good question. I don't want to dig too deep into it, but at this point in time, I really enjoy the diversity. The stuff I do at work and the stuff I do in FOSS are fairly different and exercise different portions of my brain. I think I fundamentally enjoy having that difference, although it's hard to say for sure. Even just restricting in to FOSS, I will often oscillate between different projects in order to keep things fresh and avoid burning out. For example, almost a year ago, I started working on a rewrite of one of my Rust libraries. I hit a thorny problem and my motivation waned, so I moved on to something else. I've just recently moved back to continue my rewrite, now almost a year later, with renewed vigor.
