I feel like Barry Maitland’s mum is a wise woman yes?
But Maitland makes a good point about doing something you love and doing it well, and if not… move on.
Has an author of have you held on to something when you should have let go? (I feel like Harry Dresden should have ended awhile ago.)
And that thought brings me to: should a series have a firm end? Or should it continue until interest wanes? Is it good if interest wanes?
