You're better off picking one or two that close a specific gap in your current life and getting them to run on autopilot before adding anything else. It's worth saying something about the genre itself: most of these lists aren't written for a specific person — they're built for maximum coverage, so every reader finds at least something familiar and useful for themselves. That's reasonable for an article aimed at a broad audience, but it works badly as a ready-made action plan: a plan for one specific person and an overview article for every reader at once are fundamentally different kinds of writing, and it's a mistake to confuse them.
Every new habit requires conscious effort and attention at first — a limited resource that doesn't grow in proportion to your desire to become a "better version of yourself." Trying to drink more water, meditate, read, and wake up earlier all at once splits that limited resource across four fronts at once, and none of them gets enough attention to actually stick.
The gap between two approaches to the same internet list is telling. In one, someone writes down all twenty items and tries to start on Monday — by Wednesday they've forgotten half of them, and by the following week they've dropped everything at once. In the other, someone picks one item from the same list that solves the most obvious problem right now — say, five minutes of stretching in the morning if they sit at a desk all day — and locks that in before adding the next one.
