>>248714hm depends on where you live, your budget, and what your schedule looks like.
for archery, you can get a training bow (generally lightweight, not very strong) for under a hundred bucks. pick up some arrows (practice ones, dull metal on the end instead of an arrowhead) and a target (which can literally be a cardboard box), and set up a makeshift range in your backyard. this was how i taught myself at around age 14ish.
not to hunt though, i just wanted to larp as katniss everdeen, kek. and if you don’t have the space, then there may be an actual indoor practice range nearby you can go to, but i’m rural and have no experience whatsoever with those.
sadly i have no advice or experience with guns. growing up, though, i had male friends who would practice with bb guns in their yards. but a range would def be your best option as an adult.
then, for fishing, i’d recommend picking up or borrowing a rod and reel and getting either some rubber bait and/or lures. assuming you have a license (and your location), you can visit a nearby body of water and basically just cast and reel back in for a few hours, see if you enjoy the rhythm of it and all that. i mostly did catch and release fishing as a kid, but catching to eat the fish is really rewarding. and it’s definitely a matter of patience, as another post said. you can cast for ages and come up with nothing, which is why it’s important to enjoy the motions of it beyond just the catch.
