Policeman

After finishing his second year at university Aaron quickly felt that the institution couldn't really offer him much more (Other than an actual degree) and was looking into a career in the force, ultimately wanting to become a detective living on Baker Street for a month before running out of money.

This goal does conflict with his aspiration of becoming a drug dealer which is also a prospect he's held for a longer period of time too. However Aaron did master two sports before reaching the age of 12 so achieving his desired rank in the fuzz and selling drugs illegally is possible for him.
