Spheres of Influence
Spheres of Influence, or circle of control, is a way to think about the things that you can control vs the things that are out of your control [1].
They are often represented as three concentric circles:
- Control - things you have direct control over
- Influence - things you can influence but don't have direct control over
- Concern - things you care about but have no control or influence over
This can be useful when deciding how best to focus your efforts.
