Some people make decisions after careful deliberation and then they stand by those decisions no matter what unless others convince them (also through careful deliberation) that they were wrong. If they are wrong, they are willing to admit that and then rectify the situation, with help from others if necessary. They also learn from their mistakes so they an grow as a person and as a leader.
Others will go with any idea that pops into their head, no matter how wacky it may be or how wacky it becomes and they dig in their heels in then face of evident reason when others try to show them how bad the idea is, or even how good the idea is just not appropriate for the group for which the idea is proposed. These people will often vilify their opponents and become more angry and bitter when their idea is finally rejected.
In the course of serving in a church, whether as a layperson, a leader, or a pastor you will encounter many of the latter group.
Make certain you are not one of them.
You will encounter few of the former group.
Strive to be one of those.
