Thank you for writing a post that is both optimistic and realistic. I've printed this out to have on my desk and refer to for a while. I need to add more tools to my coping kit.
I'm "only" 53 but have just gone through The Change and have spent a lot of time in despair. Doesn't help that I'm a life-long depressive. Lots and lots of regret and feeling the lack of life accomplishments like a partner and career. And feeling as if there is nothing to look forward to.
However, in my better moments, I remind myself that I'm not infirm and broke yet, though that is coming, and I must make something of my days and moments, even if doing so won't result in that partner or career.
