They say that having a little bit of knowledge can be dangerous, but they didn't say that it would be dangerous to me.
The annoying (and hard) thing about accumulating experience is that problems becomes a little more solvable every day. No matter how stuck I get, there's always that tiny string. Dangling. Waiting for me to tug on it. And I know if take hold, it'll take me a little bit further; I'll be a little bit less stuck. I know I can get to where I want to be.
I think this is what it means to be a mid-level engineer: you have the ability to solve most problems, but not the ability to know when or how to stop.
So that's the next frontier, I guess. Resisting the urge to do the one thing I just became halfway good at.
