Instead, he takes those coupons from his low-return bond and — if inclined to reinvest — looks for the highest return with safety currently available… - Warren Buffett

A by-product of our managerial style is the ability it gives us to easily expand Berkshire’s activities. We’ve read management treatises that specify exactly how many people should report to any one executive, but they make little sense to us. When you have able managers of high character running businesses about which they are passionate, you can have a dozen or more reporting to you and still have time for an afternoon nap. Conversely, if you have even one person reporting to you who is deceitful, inept or uninterested, you will find yourself with more than you can handle.

...not doing what we love in the name of greed is very poor management of our lives.

Never depend on single income. Make investment to create a second source.
