Using principles is a way of both simplifying and improving your decision making. While it might seem obvious to you by now, it’s worth repeating that realizing that almost all “cases at hand” are just “another one of those,” identifying which “one of those” it is, and then applying well-thought-out principles for dealing with it. This will allow you to massively reduce the number of decisions you have to make (I estimate by a factor of something like 100,000) and will lead you to make much better ones.
