The more you think about things and the deeper you investigate, the closer you get to realizing that most aphorisms, advice, and even "facts" are a combination of best-effort philosophy and selection biases from the lowest common denominator. Add in the Barnum effect and you end up with an ocean of inconsequential platitudes being parroted by every Tom, Dick, and Harry.

It's very difficult, requires active effort, and goes against human nature to act rationally. Most people don't even want to do it.
