Maybe you'll never find the flame that you had originally, maybe it was only because things were new or just that you'll never have a teenager's mindset again.

Maybe you'll never find the flame that you had originally, maybe it was only because things were new or just that you'll never have a teenager's mindset again. Or maybe you will if you try out new languages or new domains or new responsibilities. In my late 20s, I felt pretty competent at all the things my jobs could give me, so the only thing I could think of more was to do everything, so I became a technical co-founder. That forced me to understand and own many things that I used to take for granted or only understood tangentially, and that was quite a lot of fun. Now in my late 30s, I derive joy from mainly two aspects. The first is when I can feel the power of leverage, that I can make a large impact with a small amount of work. So that's a combination of, that my setup and my knowledge allows me to make certain types of changes and improvements quickly, and then that I can see how these changes end up having a lot of value to the company and customers. The second is when I get to solve a puzzle, so something that I know should be possible, have a rough idea of the end goal, and just having to tease out all the details and everything along the way. So I get that feeling of pushing along the edges of my knowledge, and then the sense of accomplishment at the end. If this puzzle then also has a lot of value to the company and customers, then even better.
