I would compare it to sitting in a caravan park haveing a beer watching the Park Manager talking to people in between emptying bins, and you think ahhhhh what a top job he has, until your the sucker emptying the bins working 7 days a week 24 hours a day, and not noticeing you live by the seaside anymore. Sorry to kill the romance of it, and I hope you make a squillion bucks, I just think the headache that probaly comes with it is not worth it. I dont know if you married or not or have a family, but if you do have a good look at them and ask yourself, do I really want to be away from the 12 hours a day 7 days a week while I start a bussiness that might risk there happines and the roof over there heads?
Thats not coming from any great experience in small bussiness, I have always worked for the government, (defence force, now one of the emergency services) and i really like walking out of work knowing that its no longer my responsibility regardless of what may happen whilst I am not there, and best of all, knowing that every second Friday the government says thanks for coming mate, see you next week. (and knowing how much of a thankyou I am getting).
