I lived in London for 11 years and have finally moved away from it. Initially I really enjoyed London. I liked how anonymous it made me feel. It held a certain intrigue and excitement and there genuinely are lots of exciting opportunities for the right type of person. Although I ended up completely hating London I would always encourage others to give it shot. It's not for everyone and my advice to anybody considering it to pay heed to London's sell-by date. If you start feeling you're just not loving it anymore then it's probably time to move on. I stuck it out for an additional 6 years and it really dragged me down. Moving back home to the West Coast of Ireland was the best decision I have made in a long time.I imagine that cost has already been mentioned and for very good reason. It's the accommodation that leads Londoners into the trap of living pay cheque to pay cheque. The only way around the extortionate rents is to either live in the suburbs circa zone 5 outside London City, or join a house share more central. The former solution will increase your travel costs and time spent commuting; the latter can be so incredibly hit and miss with regards to theveryone types of people you share with. We had some pretty negative experiences house sharing. My word of advice would be to avoid both an overcrowded house (4 ) or a house with a live in owner. We eventually got our own place, but that just brought us right back full circle to living pay cheque to pay cheque.London can be a very lonely city. Don't be fooled by the population. Finding a local community is tough unless you attend some sort of church, and of course that's not everyone's bag. I considered joining a choir, but even that doesn't bring a community feel because most members don't live in the vicinity of where practice takes place. In some cases participants are travelling an hour for practice. Culturally I found ethnic groups tend to stick together. Despite my best efforts to get to know a few people running a nearby store (they were lovely people) it never went past a certain point and I always felt a distance. Londoners by and large tend to keep to themselves and I found that many people we met were really only interested in keeping in touch with friends they met at Uni.Of course these are only my opinions and others may have had a more positive experience. London just became too chaotic and impersonal for me. I guess the 11 years changed me somewhat because I was so shocked at how friendly the Irish are known you return home
