to 5 is more than 20. Three to five smart, conceptual people seeking the right answers in an open-minded way will generally lead to the best answers. It may be tempting to convene a larger group, but having too many people collaborate is counterproductive, even if the members of the larger group are smart and talented. The symbiotic advantages of adding people to a group grow incrementally (2+1=4.25) up to a point; beyond that, adding people actually subtracts from effectiveness. That is because 1) the marginal benefits diminish as the group gets larger (two or three people might be able to cover most of the important perspectives, so adding more people doesn’t bring much more) and 2) larger group interactions are less efficient than smaller ones. Of course, what’s best in practice depends on the quality of the people and the differences of the perspectives that they bring and how well the group is managed.

When you have alignment, cherish it.

While there is nobody in the world who will share your point of view on everything, there are people who will share your most important values and the ways in which you choose to live them out. Make sure you end up with those people.

If you find you can’t reconcile major differences—especially in values—consider whether the relationship is worth preserving.

There are all kinds of different people in the world, many of whom value different kinds of things. If you find you can’t get in sync with someone on shared values, you should consider whether that person is worth keeping in your life. A lack of common values will lead to a lot of pain and other harmful consequences and may ultimately drive you apart. It might be better to head all that off as soon as you see it coming.
