I've lived in Chicago for about 3 years.
It wasn't bad at all. The city as pros and cons.
Good public transportation. You basically can survive without a car.
A lot of opportunities for professional growth.
A lot of fun places to visit.
Beautiful downtown, Lake Shore, Boystown.
High crime rate and a lot of shootings.
Cold, long, gloomy winter with a lot of snow.
Parking during the winter almost doesn't exist.
The city is pretty expensive.
Lack of nature.
After living there for 3 years I can't say that it's quite my place to live. I had a lot of fun there, yes but the lack of sunshine and the nature affects you in a negative way.
The city left a negative impact on my personal life but it really no the city's fault.
You can save a lot of money on not having a car and using public transportation.
