Okay, your shoes don't need to shine to be a superb leader (and remember - leadership isn't about your position, it's about the way you show up each day...so lead without title). My point is simply this: the way you do the little things displays a lot about how you will do the big things.
If your yard or home is well-organized, I'll bet your life is well-organized.
If you are attentive to details like the birthdays of your friends and sending thank you notes after every meeting, my guess is that you are attentive to the details around your big projects and best opportunities.
And if your place of business is spotless, there's a great chance the work you do for your customers has the same level of excellence attached to it (I can tell a lot about a business by the cleanliness of their bathrooms; an immaculate bathroom screams “we care” - and that caring translates into great service).
So pay attention to the details. Sweat the small stuff (like crazy). Commit to OAD: Obsessive Attention to Detail (the best people and organizations do; think Apple, Ritz Carlton, Amazon and The Mercer Hotel in NYC). Because the little things are the big things.
