Will you be clever at the expense of others, or will you be kind?

Invention requires a long-term willingness to be misunderstood.

If you decide that you're going to do only the things you know are going to work, you're going to leave a lot of opportunity on the table.

Failure comes part and parcel with invention. It’s not optional.

One of the things it was obvious you could do with an online store is have a much more complete selection.

The common question that gets asked in business is, why? That’s a good question, but an equally valid question is, why not?

When you receive criticism from well-meaning people, it pays to ask, ‘Are they right?’ And if they are, you need to adapt what they’re doing. If they’re not right, if you really have conviction that they’re not right, you need to have that long-term willingness to be misunderstood. It’s a key part of invention.
