I have a very wide area of interests, and doing things takes time. But while I'm doing thing 'A', I think about the fact that I'm making no progress on 'B', 'C', ... 'n' and it distracts me both from thinking as deeply as I need to on thing 'A' and the enjoyment I get from getting something done. So I struggle with letting go of the desire to get everything done that I can imagine would be fun and interesting to do.
Apparently that's a no-no: ... Flint replied, "Well the top 5 are my primary focus, but the other 20 come in at a close second. They are still important so I'll work on those intermittently as I see fit as I'm getting through my top 5. They aren't as urgent, but I still plan to give them a dedicated effort." To which Buffett replied: "No. You've got it wrong, Mike. Everything you didn't circle just became your 'avoid…
You go to a gym to learn to lift weights. You see a big strong guy and ask him to teach you. He must know how to lift weights and get big and strong, right? He's done it after all.
Sure enough, the big guy knows just what to do. He's got all sorts of advice, he disagrees with conventional wisdom, he shares his training schedule etc. The only problem is, when you follow the big guy's advice, you don't see much gains - or maybe you get injured, or you plateau.
What you didn't know is that, in addition to all of his advice and idiosyncrasies, the big guy takes steroids. The big guy is big not because of his lifting schedule or the chant he says before he works out or whatever, he's big mostly because he's taking steroids. Following his advice without the steroids won't really be that useful for you.
To relate this back to the Buffet story, Buffet has been rich for decades. His wealth came from his ability to value companies, make deals, etc. Then with money he lives a very different lifestyle.
If you don't have the steroids - the vastly better ability to do something the market puts a lot of value on, then Buffet's advice may not get you very much and may actually hurt you. Where Buffet lets lower priority tasks slide or delegates them they still get done by his employees. If you do it then your house is going unmaintained or a relationship is getting neglected etc.
