If you’re a leader of a ministry, an group, a church, whatever, your core activity is making decisions.
In the end, it was your decision to accept this post, it was your decision to get people on board with you, it was your decision that you’d all focus on X and not Y. You decided to take that person’s suggestion, and say no to that person’s suggestion.
You’re constantly re-stating the decisions you’ve already made. (If you think these are assumptions… You’re wrong).
If there’s a question your team can’t answer, you’re the one they turn to for a decision.
