Usually when I wonder if there's a better way to do something, I end up just searching online. Usually WikiHow can point you in the right direction, especially if it's for like basic human stuff. Since you're looking for a wiki this seems like the obvious choice.
If you're looking at building better habits like eating healthier or building a routine, I'm reading Tiny Habits right now and it's pretty eye-opening. Your mileage may vary with self-help books, but so far the science and exercises are sound.
