I know a guy whom I would call "most long-game".
Right now it seems not much of a difference (although 15 years ago he did stand out as the level head among my acquaintances). He has been working in the same lab for almost 20 years now, since highschool. Curating an ongoing series of translations for 11 yr or so - both his own and those by more suitable specialists. Collecting earlier editions (once, a single-volume survivor which he got to be reprinted and circulated). Cooking new things, occasionally.
The downside is that damned concrete mixer living peacefully in the middle of our backyard.
Characteristics like:
I'm curious about a general description of them (you should probably avoid outing anyone without their consent).
I also value a lot interacting with such people in general. I find them interesting and they help me understand a wider range of human experience:)
