You need a balance with money and family to have optimal happiness.

You get what you reap. Whatever works for you, as long as kids don't get shafted. My brother tried to have both, but the money always came first so he wound up with a failed marriage and totally estranged from his kids; I have been closer to them than he ever was. Not that it isn't possible to have both the two career, financially secure life and a good family life as well. My youngest son and daughter-in-law have done it while raising two great grandkids, but you need to set boundaries and maintain balance between the two.
