Your to-do management system says a lot, maybe everything, about you. We've organised the major systems according to their Dungeons and Dragons alignments, making value judgments with which no sane person could ever disagree.
If you've never seen an alignment chart before, here's how they work. Each chart takes a collection of similar things, and categorizes them along two axes: law vs. chaos, and good vs. evil. (Something can be lawful but evil, like an insurance company, or good but chaotic, like puppies.) The two axes are highly subjective, which is why you can apply them to absolutely anything and instantly start an argument. Internet culture encyclopedia Know Your Meme explains further.
As for our chart above, the best to-do system is whatever works for you. It's just that maybe that system is evil, and you're evil. No shade! Evil is fun, we do a whole theme week for evil every year! Embrace it, and get your stuff done.
