Sorry, a search of the Internet Movie Database (imdb.com) for "my foolish things" finds no reference to it at all.
There are nearly half a million books published every year (with just over 10% of them being fiction). Hollywood only makes about 600 movies per year (and many of those are from original screenplays, rather than based upon books), so the chances that any particular book will make it to the big (or small) screen is extremely low.
