Earlier quoted context omitted.
Health is only temporary, and everyone in your family is going to die, until someone makes a trillion dollar startup to cure aging. So it is fundamentally wrong to put health, family, and work as things opposing each other, ultimately they are all needed on a way to get all of the galaxy filled with life. And as Susan have shown one can both do great work, and have a big family with 5 children.
Why it's a good idea to fill galaxy with life? Why should we care about it? Also, seeing that our current civilization-system is already at the brink of catastrophe, we should focus on less ambitious goals, such as preserving life on Earth.
Also those two items aren't mutually exclusive. Both can and should happen in tandem. Anyone arguing otherwise is just a mentally lazy person.
