The best outcomes often come when you balance personal initiative and collaboration.
Many minds come up with better ideas than any individuals, that is clear.
But many minds staring at a big problem might not find a good way in. At the very least, they won’t find it quickly.
So it takes personal initiative from a member of the group to begin tackling the challenge on their own so that the group has a solid place to start when they collaborate.
You can solve a problem on your own. You can solve a problem in a group. But the best and fastest solutions use a bit of both.
