I don't think this is true. It makes for a nice feel-good proverbial type thing to say, but it's not literally true. ¯\_(ツ)_/¯ Putting aside physical exercise, there are countless examples of folks out there who, instead of being strengthened by hard things, are just weathered down by them. I came from a family and a community with their fair share of folks who struggled and who continue to struggle. They should be super-heroes, but they are not. Struggle often just begets more struggle.Doing hard things makes you more resilient and more able to do other hard things.
When I say "we invent our needs", I'm talking about purpose. I'm talking cosmic "need", not survival. As in the world would go on without us. As in, yes, we need to eat to survive, but the vast majority of our motivations are entirely arbitrary and constructed. As in the only reason struggle is required of anyone at this point is that we've made it that way on purpose. As in, it's counter-productive to make struggle a pre-requisite for progress or quality of life. I don't think value is naturally associated with struggle. I don't need to have climbed a mountain in order to think that the view from the top is nice to look at. I don't need to have cooked something myself for it to taste good. I don't need an artist to have starved on the street to create a masterpiece. There is no need to require that folks struggle before being granted some amount of comfort.
It's like the whole diamonds thing - where folks for some reason insist on "real" diamonds instead of lab made ones despite being identical - because people arbitrarily decided that they wanted the associated struggle. That was a choice. Somone out there had to make the internal calculation that "I don't want this shiny rock unless it was mined by child slaves." There's no intrinsic or objective value in that, but there is a clear harm.
