Beware of little expenses; a small leak will sink a great ship. - Josh Kaufman

Roughly defined, a business is a repeatable process that: 1. Creates and delivers something of value … 2. That other people want or need … 3. At a price they’re willing to pay … 4. In a way that satisfies the customer’s needs and expectations … 5. So that the business brings in enough Profit to make it worthwhile for the owners to continue operation.
