I stole this from another thread.
Is there anything you feel rather ashamed of having done or not done etc?
Mine is:
I have started but not finished The Remains of the Day, Never Let Me Go and Klara and the Sun (Kazuo Ishiguro books).
and many other 'worthy' novels.
I do have greater sins I might share at a later date.
I used to force myself to finish every book I started. These days I'm easier on myself and do not e.g. last year I got this book, read half and have put it to one side to perhaps continue someday
