Really loved this post Page.  Sometimes it takes a "huge failure" - one we can't hide from or rationalize away in our own mind - to learn the lesson(s) we most need to learn.  That we were willing to risk big enough to fail big is an indication we are ready to grow - it is a sign of strength and courage.  That same strength and courage is what we can depend on to get us to the other side.

In terms of advice to add for someone going down this road now, I'd add do what ever it takes to move past feeling ashamed.  This falls under the "know you are human" category.  Some people take themselves away with anger or bravado, but many slink into the background unable to fully recover themselves from the shame and embarrassment.  Holding onto shame not only robs us. but also robs those around us from the best of what we have to offer.  If you are a leader that people look up to it can rob others of hope.  The first step is forgiveness.  Forgiveness begins with you forgiving yourself - if you can't authentically get there, get help.  it may be the most important lesson you ever learn.
