The older I am, the more I know that I don't know...
I've also completed a year-long coaching certification program. One thing, out of many, that I learned through that is that I don't have anyone else's answers, they have their own answers. All I can do is ask questions, guide, and/or share my experiences. Each of us has to come to our own conclusions about what is right for us and our families based on our own knowledge and experience, and the resources we have to work with.
This approach has also made me sound less like a "know-it-all", at least sometimes :-) than I probably came across like when I was younger.
