To each their own. Different people have different priorities. I remember relating tremendously to the section of the HBO doc on WEB when his wife was telling the story about bringing up the pot when she was sick. Sometimes, when you are a deep dive person, the lights are on, but mentally you're just somewhere else. But personally I'll never understand not doing everything you can to be there for your kids. After a certain point, money becomes meaningless. Its hard not to judge people who spend their whole lives rabidly in pursuit of it to the cost of many of the "finer" things in life. I would never trade the opportunity to experience certain things on my own terms for any amount of money. From time to time I get offers to go work for people in the city or at an office. While I'm always flattered, the response is always the same. "Can I pickup my son from Pre K at noon? Can I take my daughter to swim lessons at 2pm on Thursday? Your answer is my answer. Thanks though."
Of course, none of this means there isn't a boatload to learn from folks who do it differently. If anything, having the roadmap of people like Buffett, who dedicate their lives to certain causes(regardless of our opinions on their nobleness) make it somewhat easier for all those that follow.
