I'm very fortunate, in a job I enjoy and get decentish money for it.
That being said, I can earn significantly more (25-50%) working further afield or in a different position (150% more abroad), but I wouldn't do it. My commute is 20 mins, I work on interesting projects, I have a brilliant view from my desk and my colleagues are awesome. Having a family having home time is important to me. I do sometimes have to travel further afield for work, or do very long days, but I enjoy those days, weirdly!
If I was single however, I'd take the opportunity to get ahead in life, beast it for 10 years then enjoy life. I did this with the kids, we had them young, got them out of the way and fine it's dented the fun of our 20's and I had to sell my cars, but i'll be 40ish when they are all leaving home and I'm still young to enjoy life.
