Too Much Pruning?

I believe it was Warren Bennis who said it's rare that we prune too much. He was talking about business leaders, but I believe this goes for marriage as well. What should we prune? Maybe start with hobbies, and maybe too much work. But whatever you do don't prune or cut away time with family and with friends. And when in doubt seek input from your spouse about what you can prune so that your marriage tree can thrive!
