it's not possible, magick cannot contradict nature, and we cannot effect time.
i was 15 once, so i'll pass on some wisdom to you, embrace the here and now. when i was a kid [about 6-7] i use to think how awesome it would be to be 16. when i was 16, i thought about how awesome it would be to be 23, and now that i'm 23, i want to be 16 again. the whole high school and homework stuff sucks, but i miss hanging with my friends, and only having one or two responsibilities. now i have a lot more responsibility, and rarely see my friends unless they come to my work. trust me, enjoy this time while you can. why do you want to jump ahead to 22 anyway?
