Never stop learning
I was futzing around with Fusion 360 today trying to get a handle on how I’m going to make my vacuum hose coupler. It’s one of those skills I kind of learned by braille. I know enough of it to be a little useful.
That’s the thing though — it’s learning. You should never get to a point where you stop learning. Even if it’s not in your “field” or whatever. Just keep using your brain so you don’t lose it.
