I have a long term goal of reading through several lists of books:

• Time Magazine’s Top 100 English language Novels 1923 - 2005 (78/100 read)
• Modern Library’s Top 100 novels (43/100 read)
• All Pulitzer Prize Winners in fiction (17 read so far)
• All Booker Prize winners (5 read)
• BBC’s 100 Most Inspiring Novels (23/100 read)
• 2022 Big Jubilee Read (8/70 completed)

But, I mix that with short term goals:

• Read 24 books a year
• Read for an hour a day, 6 days per week.

I'd say most books I read aren't on any of my bucket reading lists, and I tend to mix long books with shorter ones to reach annual goals.
