one of the most crucial frames of mind to actively apply while either visiting or living in rio de janeiro is that it is unlike any other metropolis in the world - the 'marvelous city' is a unique entity of its own, which requires an open-mind and a certain level of tolerance to truly absorb all that it has to offer. 

it would certainly be a pity for both short-term and long-stay visitors and a great disservice to their experience, if the time is spent comparing rio to another city - it is very important to be present and to live in the moment because the rhythm of the city is in constant motion. 

this approach allows the reception of carioca people and their customs, the beautiful city and state, and of course the tropical climate, all thing that could potentially be a major culture shock - while it is very easy to remain in one's comfort zone, rio de janeiro should be incentive for change, and it is the perfect place for a foreigner to be receptive and have a truly unique experience.
