I believe, as I am getting old, I have increased my insecurities in some areas but also increased my confidence in others. So I would say I am in a neutral position.
I consider my insecurities growth due to aging and lack of the physical condition I used to have. My confidence growth comes from learning many new skills (most of them way more physical than skills I have learned and developed in the past) after I bought the farm and decided to get quite involved in in the renovation of the building.
Isn't it kind of funny that most of us have been told to "get educated" for a good life, but a good life tends to come from pretty physical activities which most avoid now?
