I hear you. I miss the frenetic pace and zeal of my 20’s. In my 50’s I find myself fighting the lethargy and then realize that I have the possibility to be more present than ever before. While I exercise that muscle, I will take the advice of the others and exercise, learn something new, and act on something meaningful to me. Meanwhile, know we’re sharing a path and I’m rooting for you to find a happy balance as will I.
