I've spent 15+ years building things — software, products, systems, teams, processes — and I still haven't figured out which one I like most.
I think in systems. I notice when a plate is wobbling before it makes noise. I ask too many questions on purpose, because the right question is usually worth more than the right answer.
I'd always rather believe my work is honestly helping a human. A lot of jobs exist to make wealthy people wealthier, and that tension is worth naming.
Something I don't hear talked about enough: you don't owe your employer anything beyond what you agreed to. At-will employment is the foundation of the US labor market — they can let you go tomorrow, and so can you. That's the deal, written into the standard. Companies are especially good at obscuring this. The mission statements, the culture decks, the "we're a family" energy — a lot of it is designed to manufacture loyalty that only flows one direction. Too many technical workers are really good at their jobs and really bad at remembering that the transaction is mutual. Your skills built that product. Those skills are yours.
Always thinking about what comes next, except for when I am pondering the now.
