Sometimes I receive letters from readers of my Senior Living column, asking for advice. Today, in lieu of a regular column that involves research, I am sharing some of this correspondence.

Dear Liane:

I play in a tennis doubles group once a week and I’m not a good doubles player at all. Also, I am writing a book, although I don’t call it a book, I call it a project because retired people writing books is an embarrassing cliché. But it is, actually, a book, and even the people in my writing group are not enjoying reading it. My question to you is this: Should I give up these pursuits? After all, I am 65 and really, what’s the point?
