@Purple @kitcat To say nothing of when you've faced a problem, figured out a fix, and can *actually explain why that fix is correct*, and *apply the same reasoning in other situations*. Not just the same fix, but the same *reasoning*.
Maybe I'm old-fashioned like that, but actually having figured something out brings me joy. Even if it is stuff that lots of other people know. Learning how the pieces fit together to bring the result I get out of the thing I made.
