I have learned more in the last 8 years than I have at probably any other time of my life. Watching my family tear itself apart, losing and finding a new job, coming to an uneasy peace with a new faith I may not be fit to carry... I learned a few things about doors, both opening them and closing them. I've had my heart broken three times by people I love but each time the hurt becomes less and less. To be fair the people that did that were suffering from their own problems and demons and maybe broken hearts of their own. I suppose I did well, managing to make it well into my 50's with an intact heart. Many men don't make it half as long as I did.
One of the biggest lessons I've learned is that some doors are probably just better left shut.
