BBC London marks 1,000 days to go until the 2012 Games with a series of personal films by some those who believe they will gain or lose out.
Kieran Shekoni is a talented 19-year old from Clapham who enjoys producing music. As a former Fulham Junior player, he also likes a kick about with his friends.
After leaving college with a keen interest in sport, his friends suggested he apply to the school leaver program at LOCOG (London 2012 Organising Committee of the Olympic Games and Paralympic Games).
After several interviews and training days, Kieran and nine other leavers were given full-time jobs working in LOCOG's Canary Wharf office to help organise the 2012 Games.
Michael Jones is a Greenwich entrepreneur and family man who owns a butcher's and cheese shop a stone's throw from the historic park.
He fears that the Olympic plans for his area will have an adverse effect on his business.
He reckons that the traffic increases will cause major disruption, and is unhappy about proposals to transform the park into the Olympic Equestrian centre.
London 2012 say the entire Park will only be closed for four weeks and there are no planned residential road closures.
A spokeswoman added: "There will be huge benefits to local shops and businesses with the additional visitors coming to Greenwich."
Dalawar Chaudhary is a Southall entrepreneur and restaurateur who already caters for the Pakistan cricket team, and now aims to extend his hospitality to the Pakistan Olympic team.
Dalawar believes that Southall is the best home for the Pakistan Olympian families during 2012, and has played a key part in the bid for the team to train, live and dine in Southall.
Dartford resident Paul Horden sees the arrival of the Olympics in London as a fantastic business opportunity.
By buying several web domain names, he intends to run a site where he can rent the ex-council homes belonging to himself and his friends and family to Olympic visitors.
Paul believes that Dartford's fast-track bus system and Bluewater shopping centre make it an ideal place to be based for the Olympics.
