> I spent several hours fixing a problem and I learned next to nothing in the process. This trick is unlikely to be useful again. By the time I encounter something similar, it is likely I will have forgotten about the solution. So much of modern programming in general is like this because of the always changing languages, libraries, tools, software, hardware etc. such that when you're coding you have to accept it will keep happening occasionally no matter how experienced you get so you don't get too wound up about it. It's especially discouraging when you're starting out too and don't know this yet.
