While I think Nicklaus' mindset is commendable, I also think there is a real danger trying to think his lessons are widely applicable.<p>Jack was <i>by far</i> the best golfer of his era, and he made many millions of dollars playing a game he loved, so he could easily afford things like having his family travel with him everywhere. For nearly all others caught up in the rat race with an unhealthy work-life balance, they can't say the same.<p>I'll just speak personally for myself, but I know some of my tendencies to over-commit to work are because I, just like Jack, want to be really great at what I do. But at the same time, I don't have anywhere near the same level of comparable talent in my field, so I have to work much longer at it, and I'm still rarely satisfied with the results.<p>It kind of reminds me of stuff I've read about Usain Bolt, that he's really chill and laid back. When you know you have the innate gifts to never lose, it's easier to feel that way.
