If you marry someone with a big career and you want to have a big career you have to find that rare mate who can treat you as an equal, even when your career needs to come first. These are very tough marriages to hold together because there is a constant, never-ending re-balancing of priorities and power between spouses.
If you marry a breadwinner who expects their career to come first, then things will probably only work if you can support that. Even if you have a career of your own. This is the easiest marriage to hold together (if any marriage can be called easy) as long as the man is the breadwinner.
If you marry someone who is terrible at earning money, or someone who is good at earning money but doesn’t want to, then you will have to take responsibility for earning the money.
In each of these cases, your career decisions are largely determined by who you choose as your mate.
