Most of us had parents that made mistakes. Some of those mistakes hurt us, stunted our development, or damaging our psyches. When we become parents, we try not to make the mistakes that our parents make.
But the problem is, there's more than one set of mistakes. In fact, they often come in pairs. If you move too far away from one mistake, you may not wind up in the sweet spot. You may be doing the other mistake.
In Zion National Part there is a hike called "Angel's Landing". You wind up on this ridge, with a 1000 foot dropoff on one side and a 500 foot dropoff on the other side. If you move too far away from one cliff, you fall off the other.
Parenting is like that. Take permissive vs. discipline, for example. If you avoid discipline too much, you may damage your kids by being too permissive.
