I want to be an adult

I want to be an adult.
Because adults can do almost everything what they want to do.
First adults can cook when they want.
I want to cook but I can't cook,because it's dangerous to use stove.
Second I have to study but adults has freedom of study(but my mom said that adult should study sometimes).
When I grow up I will study only I want.
Finally I can do what I want.
If I were an adults now, I would be a youtuber,and go to bed when I want(Now I sleep at 10),and use my cellphone whenever I
want.
That's why I want to be an adult.
(But I don't want to that my parent get older.Don't you have any way?)
