It's obvs that old balls did what he did because he was in hurry-up-fam-mode due to his old balls and all. Pair that with your 80-hr weeks and the fact that you just grad'ed and started this career so the 80-hr weeks won't be going away anytime soon, and that prob made the decision for him.
Hard truth: 80 hr weeks don't mix well with long term relationships. at that pace, your job is your long term relationship.
I used to do it and it was unsustainable for my family.
Also, chicks that are strong in personality, independent, and confident make the kind of girlfriend that is also a good friend-friend for a guy. Makes for a better base for the long term relationship.
I wouldn't agree with any of the advice that includes changing anything about personality or tendencies, however, you need a guy who understands ambition and that is usually one with ambition, therefore the ones working similar careers with similar demands upon them.
