If you’ve invented something new but you haven’t invented an effective way to sell it, you have a bad business—no matter how good the product.

Like acting, sales works best when hidden. This explains why almost everyone whose job involves distribution—whether they’re in sales, marketing, or advertising—has a job title that has nothing to do with those things.

Anyone who can’t acknowledge its likely effect on himself is doubly deceived.

Most fights inside a company happen when colleagues compete for the same responsibilities. Startups face an especially high risk of this since job roles are fluid at the early stages. Eliminating competition makes it easier for everyone to build the kinds of long-term relationships that transcend mere professionalism.

Max Levchin, my co-founder at PayPal, says that startups should make their early staff as personally similar as possible. Startups have limited resources and small teams. They must work quickly and efficiently in order to survive, and that’s easier to do when everyone shares an understanding of the world.

You’ll attract the employees you need if you can explain why your mission is compelling: not why it’s important in general, but why you’re doing something important that no one else is going to get done. That’s the only thing that can make its importance unique.

Since time is your most valuable asset, it’s odd to spend it working with people who don’t envision any long-term future together. If you can’t count durable relationships among the fruits of your time at work, you haven’t invested your time well—even in purely financial terms.

To anticipate likely sources of misalignment in any company, it’s useful to distinguish between three concepts: • Ownership: who legally owns a company’s equity? • Possession: who actually runs the company on a day-to-day basis? • Control: who formally governs the company’s affairs?

You need good people who get along, but you also need a structure to help keep everyone aligned for the long term.
