I used to have that passion. Every waking moment devoted to figuring out cool things. Or at least what seemed cool to me.
Then one day I joined a rocketship company and all my side projects and ideas started to feel small, boring, and insignificant. The grandest idea I could come up with couldn’t hold a light to even the most mundane problems a real business in the hockeystick part of the curve comes up with.
Sometimes I miss the motivation to tinker. Sometimes I cherish my newfound ability to relax. Perhaps one day I will tinker once more.
