How to do this is of course hard. Meditation helps me. Relationships. Balancing my consumption of news. Staying away from histrionic people that drive that anxiety (read Twitter). Taking a break from that which bothers me (developing hobbies and other interests).
Even as I get older I increasingly have a sense that all attempts to control will be resisted by others. Even when you have their best interests at heart. People willfully, sometimes ignorantly make their own big mistakes to resist being controlled. Sometimes though we’re not as smart as we think we are. This applies to so many situations, including work, politics, and parenting!
In work situations I am conscious more and more of wanting to lead by following, stepping back, let other people be in charge and get the glory. It’s really the most sustainable path for a sane life. Instead of doing, teach. Instead of teach, listen to other people’s wisdom. Paradoxically by being silent and non-action can sometimes have the biggest impact.
