I don't automatically think of hobbies as being something trivial...but it depends on what you're comparing it to.A word has connotations as well as denotations. This is one of the ways we create shades of meaning—and understanding. Those shades matter. All sorts of terrible things can happen when we ignore connotations
the word “hobby” connotes triviality, among other things. I personally don’t think it’s trivial so I don’t use that word. And when others call it a hobby, I am not offended (a word that has taken on connotation of oversensitivity and self righteousness, recently ) but I do wonder, why would they it think it trivial? And: do they REALLY think it’s trivial? And if they don’t think it’s trivial, why use that word? The possible answers make me avoid the word “hobby” all the more
Everything about pipes and pipe tobacco is trivial compared to genuinely important and significant things.
But then a certain amount of triviality and amusement is important and significant for sanity retention.
