Your circle of influence:

The idea behind all of this really is that you design your own life by focusing your time and your energy on things that you can do something about!

The Circle of Influence represents all the things in our lives, both personally & professionally that we have absolute control over. Things like our attitude, body language, choices, things we say, and our behavior would fall within our circle of influence.

Proactive people tend to focus on things in their circle of influence, things they can actually do something about. 

Reactive People focus on the circle of concern. As a result, their circle of influence can shrink.

Habits & Routines

When you're dealing with difficult situations, think to yourself, "Is this in my circle of influence?" And handle it accordingly. Start chain reaction with small actions.
