It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.

The thing that cripples communication saturation is specialization — the number of roles and titles in a group. If people have a special title, they tend to do only things that seem a match for that title. And to protect the power of that role, they tend to hold on to specific knowledge.

So we got rid of all titles. I called everyone and told them to rip up their business cards. If someone wanted to put a title on their resume, they could do it for external use only. In here, where the work was done, there were only team members. (emphasis added)
