I worked for two years in Canary Wharf and didn't change my lifestyle so I was able to save some money. I just announced I was quitting this week and I am currently trying to think about what to do next. Which can be pretty much anything. It's hard to decide what to do next when there's no limit.

Most of my friends did change their lifestyles while working in Canary Wharf and when they decided to leave they had no money at all. I'm glad I avoided that.
