For anyone who thinks that learning something new (like playing organ) and finding happiness again is too late for them, refer to this article.
I feel quite sad looking at many seniors who just watch TV all day or complain how their lives are miserable.
Happiness really is much more internal attitude than something external.
It simply shows if we have found meaning in how we spend our days or not.
So I suggest we keep looking.
