This. I learned programming the "bang your head against the wall" way, and I think I'm much better for it. I'm much more familiar with the innards of my tools, operating systems and programming languages as a result, and I'm much better at debugging things and understanding what's going on when I write a certain piece of code. I also have a pretty diverse set of skills. I find that any information you pick up somewhere eventually ends up being useful elsewhere.

But I'm privileged in that I wasn't ever pressured to learn, it wasn't a point where my livelihood depended on it, so that's a factor.
