Useless classifications

We like categorizing things: 3 types of innovations, 5 types of methodologies, 10 types of styles, ad infinitum. Most of them waste time that's better spent on meaningful goals.

Consider a kid who wants to play soccer. "You first need to understand the different types of games, and where soccer fits in," goes the coach. Should the kid start "learning by playing," or waste 3 years learning useless theory that's not worth a wooden nickel? Yet wasting time on theory is what we do in this "information age" that rewards quantity of data rather than quality of insights.

Why not just create, construct, build whatever you feel like without the need to "classify" what you're doing?
