I'm this way, and I don't know why. I try to avoid frontend, until I'm more or less forced into it. I can make something functional, but inevitably get grilled about my way of going about it or why I didn't use 2018x style. The fact is, I don't care. I hate every minute of it, and only learn enough to knock it out. I find myself mentally complaining every step of the way. I just don't like how the web as it is is designed, written, or fits together. I wish there was an off switch, as I know i'd be more valuable with these skills, but I'm just mentally unable to accept it.
