Barrels and Ammunition - Keith Rabois

Turns out that any organization can  only really do as many projects  as it has barrels. Those are the people  that can come up with original ideas can  rally  the team around them, and can fix things that  don't look like they are  working as  promisingly as you had hoped.

Most people in most companies are  ammunition, meaning  they will do what they're told and they  will try to do it to the best of their  abilities,  but they won't actually drive from  inception and conception  and take an entire organization with  them.
