How can I wait another 2 years and 10 months until my 18th birthday?

I'm 15 and I want to be 18 because I feel like these years are being wasted and somethings that I am not allowed to do/forced to do are not in my will, and my philosophy of life is "Do what thou wilt" Please don't answer like somebody trying to proselytize me. I do not want to "prosper" or be "successful" I want to maintain myself and do what I want. But what are your stories about how you managed to wait to be 18 to move out, etc?
