The difference between successful people and really successful people is that really successful people say no to almost everything. - Warren Buffett

We prefer: large purchases (at least $5 million of after-tax earnings), demonstrated consistent earning power (future projections are of little interest to us, nor are “turn-around” situations), businesses earning good returns on equity while employing little or no debt, management in place (we can’t supply it), simple businesses (if there’s lots of technology, we won’t understand it), an offering price (we don’t want to waste our time or that of the seller by talking, even preliminarily, about a transaction when price is unknown).

Losing some money is an inevitable part of investing and there is nothing you can do to prevent it.

Do what you love and work for whom you admire the most, and you've given yourself the best chance in life you can.
