This really hit home with me. For a while now, whenever I've been coding, I've been more focused on learning new things instead of creating things. While this isn't necessarily a bad thing, I had project for a CS course that I didn't end up doing so well on, and I attribute that partly to me not having built something in a long time.
I'd like to change that this year. When he posed the question "What was the last thing you built that gave you that Builder's High?", I sure as hell couldn't remember much that I've built recently that gave me that feeling.
