Hey Caroline,
Retirement is a wonderful time to transition. I too have my occasional regrets and wishes about the past but nothing to be done about that now but learn from it that there is no better time than NOW. Retirement meant more freedom to be me. No bosses, clients or coworkers. We own our home and I feel good about our future security. Of course we still want to get along with people and be treated with kindness and respect and you are already experiencing that. In retirement we also have more time for any number of appointments to see all the people who help us along the way.
Welcome aboard and let us know how you are doing, please.
