The problem with this phrasing is it implies that motivation is an inherent aspect of individuals. Nobody is a do-er. Motivation is impacted by a variety of factors.
Personally I can’t NOT do things. Regardless of if I get paid, it works out, or I even get yelled at for doing it - I fix things, pull things apart and make them better, clean things up, learn, and solve problems regardless of the discipline. If I’m not doing those things, I feel terrible. If I do those things (and the more the merrier), I feel good. I’ve built large scale engineering teams at FAANG’s and laid (inspected) foundations for buildings I’ve made myself without error - concurrently.
It pays well, if I’m smart enough to do things that provide value and most people can’t. But even if it doesn’t, I can’t help myself.
So far that includes networking, electrical (permitted, household and commercial), coding, welding, machining, commercial contracts, logging, real estate investment, piloting small aircraft, rock climbing, concrete work (inspected, residential and commercial), fathering 2 healthy strong and well adjusted boys, framing, hydraulic engineering and water delivery design, teaching and mentoring many strong leaders, bespoke financial instruments, and many more. All at a level equivalent or exceeding highly rated professionals or successful folks I’ve worked with or partnered with. It’s weird, but it is what it is. I can’t help myself, and it feels almost like a disease sometimes. I did El Capitan (Mescalito) solo aid in my early 20’s for my first big wall, ‘off the couch’.
It causes friction because either people don’t believe it, or once they do they can’t understand it - sometimes they even get angry or resentful. I don’t do it because I’m trying to show off. It just is who I am.
