Patricia that is such a wonderful reply. I'm like you, my life, though not frenetic compared to how it was in my teaching days, is nonetheless full and demanding.
Like you, I get tired, but then if I trace all I have done in a day, write an article here, answer some emails, edit, walk, exercise, do washing, cook, etc etc, catch up, it's pretty much a full life.
As for making the world a better place, I am sure your job as a psychotherapist allows people to move along with their lives. And if that's not making the world a better place, I don't know what is.
And though there is still much beauty in our world, I do wish we could be instrumental in having people set aside their differences and enjoy whatever time they have.
