Dude, making a ton of money is no where near the most important thing in life. I created a flexible job for myself, and the good thing about it is I have seen almost every single CC meet, indoor and outdoor track meet, dive meets, etc. that my kids have ever been involved in...the ONLY time I miss something is when they both have something in different places at the same time.
Working 60-100 hours a week is CRAZY!!! Dude, you are only on this planet for 100 years if you're lucky. People who work like that are chumps. Don't do it.
The reason MOST couples who fight about money do so is NOT because they don't make enough money...it's because they have chosen to live a lifestyle that is not supported by their income. If you make $40,000 a year, then you need to rent an apartment or buy an $80,000 condo. Just because a bank might give you a loan for some bigger amount doesn't mean you need to take a loan for that amount. Save up and pay for things...NO DEBT. I didn't have cable television (except for one year) until I was 41 years old! Not everyone gets a smart phone or cable or the fastest internet connection at home. Live WELL within your means, budget for things you REALLY want to do (vacations are important to me, so we ALWAYS take at least one each year, but we budget for them).
It's easy to not fight about money...husbands and wives need to be on the same page financially, and you make a budget based on your income, and you stick to it. Simple as that. Each gets some "blow" money each week to spend on whatever they want, but it all has to fall within the budget.
Go get a 40-hour-a-week job, leave some time for a girlfriend so that she can see you will have time for her and some kids later one, and be happy.
Working a lot? What the hell for?
