A simple but powerful observation from John Collison (external link) that I’ve come to appreciate more over time:

As you become an adult, you realize that things around you weren’t just always there; people made them happen. But only recently have I started to internalize how much tenacity everything requires. That hotel, that park, that railway. The world is a museum of passion projects.

The line at the end is one of my favorites (highlight mine). A grateful nod to the hands that build my world, and a quiet nudge to put something back (external link) .
