You can certainly be successful and be a good parent, but one of the first steps is recognizing and picking out the false prophets. You can't hold yourself to a superhuman standard, which is what a parent maximizing career while letting family malinger will present. They will say, Look at me, a captain of industry with vaults of gold, who has the physique of a twenty-five year old and is also an all-star parent. And you have to figure out that it's a lie.
One little clue - start to notice: of your professional idols who are good parents and seem to have it all, how many have a spouse working a demanding full time job as well? I realized for me it was zero.
