I could go through my life constantly weighing every purchase against the good it could do, but this would make me miserable.
You could be weighting less frequently (there is little value in reevaluating essentially the same decision too often), and it’s not axiomatic that considering the decision would make one miserable. The tradeoff is real, so if at all possible (without sacrificing the correctness of decisions about it) one should learn to become comfortable with its existence. (I expect it isn’t possible for some people, which is where workarounds become relevant.)
