Well this is how I see it. Many people miss out on what could be a great family life, they miss out on their childrens lives as children in order to provide all they can and the very best, when at the end of the day most adults look back and say 'yeah it was nice we had everything we wanted, but what we really wanted was my dad to be home more'. Dad ends up regretting the missed 'years', and the kids feel they never really knew or had much of a father growing up. He was there sometimes and we'd go on a trip once and a while, he was on his BB most of that trip... and so on. Just the bread winner, just the man who made sure we had the roof over our heads. So it's a very hard call.
It's no different in my mind than not being 'plugged in' to your children when they're small. You still have a large gap that they will feel regardless of what you were trying to do with that time.
You can be happy with what you can do and what you have and put your efforts in life itself, or you can charge headfirst into a very successful career to make the most of your families lives, but is that what they will want?
I struggle with the concept, neither me nor my spouse are college grads, I've taken a few courses and he started working after graduating high-school. He had no choice and I made bad choices. But if either of us were working 10 hour days, it wouldn't work, period. I struggle thinking because I didn't pursue higher education my daughter isn't as likely to, that's bogus though. I struggle thinking we don't make enough to really give her everything, but again, at the end of the day the very best thing we can give her regardless of whether we win a mega lottery or bank 6 figures, is.our.time.
So it's you man, it's all you. These are your wants and needs, and I think in order to have a fulfilled life you need to balance it, that usually means your career takes the back seat, as it should imo.
Good luck with all you do =) You need to do whatever is going to make you happy. Often times that includes sacrifices we'd rather not make.
