There's an aspect of "grit" that I feel is abused by the hustle-porn group. True grit IMO has an aspect of patience, it's staying w/ something consciously until it "unlocks". This can be driven by patience & respect (e.g. gardening) or by desperation or narcissistic wounds.
Consistent progress, like consistent returns, is a red flag for a ponzi scheme of sorts. You think you're growing something like an investment but you may just be borrowing life energy from other people(indirect slavery) or from the future.
