Probably a silly question but yea. What are some ways to have fun?

I try to have fun but I feel like I've never really had fun before so I'm curious what everyone else does for fun. I don't get out much though. So yeah. I really wanna snowboard, travel, do something insanely silly and make tons of people laugh, learn about new cultures, and stuff. Yeah, stuff. HEHE. But seriously I dunno if this stuff could be really considered fun fun. I wanna have insane uber fun like I'm never gonna be young again kinda fun. I'm 23 and I feel like an old man cause I haven't done anything fun really.
