The problem is, erik, that in any high-flying MC firm, you'll be working with highly ambitious, competitive, ruthless yet insecure over-achievers. Yes, the lot of them.This, combined with extremely dominant, egotistical Partners who have a chip on their shoulder even though they have 'made it' in a financial sense only, leads to a sort of 'abuser-abusee' relationship in which the gophers such as yourself are the 'abusees'.So, how does one manage one's personal life in such a situation? Well typically it's done through a combination of Hotmail (or whatever free web-based e-mail service your company hasn't blocked) and short but frequent phone calls home (i.e. whenever you manage to escape from your desk for 45 seconds). Yes, you will lose a lot of friends in the process - if you hardly ever see them, it's inevitable!I personally look back on the experience wondering why on earth I ever used to spend 80+ hours per week ordering take-aways to the office at 11pm at night with a bunch of metrosexual foreigners I neither particularly liked nor would keep in contact with after the project ended. I used to fantasise about being one of the admin staff, earning a not-dissimilar salary yet having the joy of working with normal colleagues with whom I could identify and shared a common view of the world, not to mention getting to leave the office and actually enjoy living life in the evenings.Regarding exit options, it rarely works the way you described. Sure a top-tier MC looks good on your CV, but quite frankly if you're planning to move back home in Scunthorpe or wherever it is after 4 years or so, any decent firm will probably be looking for more experienced folk anyway (and I mean 15+ years of experience). And besides, after a while you lay down roots in London, you get used to the salary, you feel like you "can't" just leave and go back to where you came from. Ask anyone who's done it, they'll pretty much confirm what I'm saying.So what to make of all this? Well, take it as you will. But, if you seriously want to have a true work-life balance (by your definition, not the firm's), then I personally think you would do well to avoid the supposed glamour of the high-flying, jet-set, 80+ hours metropolitan city slicker lifestyle, and think long and hard about going into something which isn't destined to be a 'crash and burn out' affair from the very outset.
