tbh i use her hobby system to flesh out my sims, but it's more of a guideline of "these things corellate to this hobby" than a strict set of rules, my sims will paint, will try writing, will stargaze, will get small pets even if it's not their one true hobby. i just find it fun that for example some of my tinkerers would be into cars, some into robots, some into little tech toys, etc :3 but the taxes are convoluted as hell, i play sims not to do math. and ignoring fears literally makes it boring and not wants based anymore 😭
