moving out of home

i am planning on moving into the city CBD.
my work is there, all the parties are there, all my friends are there.
i have lived with my parents my whole life.
typically my parents have always done the washing / cleaning / cooking / ironing. yes, i know, i really am that useless.
my parents still want me to stay with them though.
im 21 and i can easily afford to do it.
are there any tips for me guys and gals?
what age did you move out of home?
was it worth it for you?
is doing the washing / cooking / cleaning / ironing really that much of a hassle? is it worth the freedom?
curious to hear the stories and experiences, good and bad.
