Only from strength Most people think they know what they are good at. They are usually wrong. More often, people know what they are not good at—and even then more people are wrong than right.

Eating your own dog food Eating your own dog food or “dogfooding” is the practice of using one's own products or services. This can be a way for an organization to test its products in real-world usage using product management techniques. Hence dogfooding can act as quality control, and eventually a kind of testimonial advertising. Once in the market, dogfooding can demonstrate developers confidence in their own products.
