Hobbies for 14 year old?

so like it says i'm 14 and have no CLUE what to do.... i was gonna join gymnastics but that won't work. i want something active, i am homeschooled so nothing in school and also i'm to old for sports (i want to do volleyball but i don't think it'll work) i don't want anything crafty, i want active, i could do horse riding but my horse is to stubborn and hard headed to make it fun!!! So what could i do??? thanks!
