For travel there are probably many destinations in your own country, that people actually visit your country to see. Those a typically cheaper to do. Then there is asia - I’ve traveled tree months in asia for the same budget as 10 days visiting the States. Also in general very much depends on how/where you say. Hotel in Auckland vs pet sitting gig for a week 15 mins outside of the city (housing for free).

Same for hobbies. Depends so much on what you pick for a hobby.
