Re: I'll never really understand...
I was offered a job by the head of a small(ish) company. When I quickly turned it down, the head asked why: I said I didn't want to spend my life living out of a suitcase.
A few weeks later, I was recalling this conversation with one of the company's engineers, who happened to be onsite. He said he'd lost two girlfriends from being on the road all the time and only ever saw his flat on a Saturday night when he was home to do the laundry, ready to go away again Sunday afternoon.
Sure, I could have earned a shed load more money working for that company, but what's the point of earning all that dosh if you never have any time to spend in - either yourself or with friends or someone special?
I don't own a fancy car. I don't live in a mansion. But I do have a happy life.
