Growing up?

Hello beauts!
I've come to that stage in life, where every teenager wants to become an adult. I am 17, which isn't too far off adulthood, but still too far away. I don't want to become an adult just to be able to drink, go clubbing, watch 18 movies at the cinema without having to take an adult, buy cigarettes or drink, but to have the independence that comes with age. I'd absolutely love to have a job, sturdy annual income and the ability to just pick myself up and go places. Every teenager/young adult has times of experimentation, with drink, drugs, sex etc. but I experienced that at a much younger age, so the thought of growing up for me is just purely to have my own life, not one that has to be shared with mums. But don't people say that teenage years are the best years of your life? Doesn't feel like it! Would love some comments below so I know I'm not the only teen that feels like this?
G'day xx
