Improvement. I am, to a fault, obsessed with optimization and impact. For myself, I am always trying to understand what the best balance is so that I can be most productive and do the best work I can (e.g. balancing diffuse and focused modes of work, writing a lot to make sure that my ideas don’t get lost, etc). But socially especially, I am obsessed with understanding how we can do the most good, and how I can specifically make the greatest marginal impact possible. If I work at a company that’s doing great work, but I am a cog in a machine where my value over my hypothetical replacement is negligible, then I’m not really contributing that much marginal impact. I’m the kind of person who wants to see the calculations behind whether I should be donating bed nets to save lives today, or donating to malaria vaccine lab to save some expected number of lives in the future.
