Asking for definitions of what people should do, when ultimately the individual will be the one who will have a choice to make regardless of the circumstances,

Asking for definitions of what people should do, when ultimately the individual will be the one who will have a choice to make regardless of the circumstances, seems like yardsticking to me (that's what definitions are used for, right?), though I suppose I could wonder about that too. I also suppose I could wonder about how many aspiring/(non)tenured PHD's spend their entire lives producing publication after publication without an inkling of fame or any major contributions relative to those of the likes of Higgs (or in general, anything any individual decides to do in the spectrum of their peers), who think that they haven't wasted their life.
