As with anything in life, it conforms to your expectations of it, and those will govern the reality you get. I have travelled to many cities around the world, and have generally had really good experiences in all of them, in spite of any negative comments others have made. I also lived in a foreign country for a while (France) and was told that the people would be xenophobic and rude and that there would be lots of bureaucracy. That wasn’t the case at all (people were friendly and very obliging, and I had no bureaucracy at all) and I do believe it was down to conscious positive beliefs I cultivated in the run up to moving there.
Here’s another example. When I travel I stay in backpacker lodges, and make my decision based partly on reviews on the booking site. On one occasion, I booked up a stay in Miami despite the reviews saying that the hostel was dirty and noisy, and the bed uncomfortable. My thought form was along the lines of “ I always like the places I stay in, “ and that’s what I got. Nice room, comfortable bed, away from the bar so no noise, and I met some cool people too.
Before you do something which may be challenging, intend a good experience in advance. Intend and expect your airport check in to be easy; intend good weather on your holidays; intend the bank manager to be cooperative; intend your boss to be the same; or intend good service in shops and that’s what you’ll get.
As for cities, they are multifaceted things where any type of experience is possible. Think of the episode of The Simpson’s where the family visit New York for ten day. Homer is negative, whereas the others are looking forward to it. They go on Hansom cab rides, watch a show, see a lovely sunset etc, whereas Homer visits grimy areas and meets criminals. All conforming to expectations. If you wish to move to another city, consciously expect it to be a great place to live, and everything will fall into place for you.
