The story...
A wise boss once told me to focus on the 20% of the stuff that's within my control, or that I can strongly influence, to get the best results - the essentials. Let the random variables bounce around within limits and trust our capable people to address the minor issues as they arise. Our competitors can waste their time focused on the trivial and wear themselves out trying to control the uncontrollable - "We'll eat their lunch."
Steven Covey developed a useful model of three concentric circles that illustrates how we might best classify issues within our mind. The innermost circle contains issues that are within our control - it's small. The next bigger circle contains the issues that we can influence - it's bigger. The next bigger circle are those issues that we are concerned about yet we can't influence or control.
The only church in town will focus on the essentials for growing each person and the group too. They'll speak to concerns outside their influence and control yet they won't stay there. They'll trust the power of God to work out His will in those matters - He's fully capable and trustworthy of managing His creation. His circles have no boundaries.
