Moving To Central London At Seventeen...?

This Summer, I am hoping to leave home and move to Central London. I am hoping to house share, and have already viewed rooms in a few properties; for which the weekly rent has commonly been between �120 and �160. I will have two jobs - working in a high-street clothing shop and a record shop - which will be funding my rent and other costs, such as food, supplies, clothes etc. The issue is, I am only seventeen. I will be transferring to a Sixth Form in Central London to continue my A2 Level studies, therefore I will only be able to work after school has finished and at weekends. However, the whole point for my move to London is to experience life: I have always lived in quiet areas and want to be able to have vibrant things on my doorstep. I am very mature for my age, I have my head screwed on and I am thinking realistically about this decision. It is something that I am planning meticulously. All that I want to know is, does this sound impossible to you? Can I juggle school and work, whilst also having the free time to enjoy myself? Do you think that I should stay at home until next year when I am eighteen and I will be leaving anyway for university (Hopefully, UCL!)? Is this unrealistic, and merely a dream? Thanks.
