To complete hobby chapter you need a sim that can start a hobby and do to first chapter.
do you have grown up children waiting to be promoted? If so you can swap one thru the portrait and promote a new sim to complete hobby chapter then return them and make your original sim active again.
if all your sims have each completed every single hobby available to them and you have no children waiting to be promoted then only option is to retire and promote a new sim, start a hobby going. You can complete to first chapter very quickly.
it would be nice to have an optional button to remove and replace a quest with a new one for players getting stuck on earning the rewards!
@loliloliloliluuu just make one of your Sims temporarily start another hobby and as @SaphireandSteel says, make them complete the first chapter.
