Ten half-read books look busy on a shelf. One finished book actually rearranges something in your head.

Collecting is easier than finishing, and it produces something visible, which is most of the appeal. A book does its real work in the last third, where the argument lands and rearranges what you thought before you opened it. Stopping early leaves you with the flavor of an idea and none of the change it was built to make.

Choose the one you are most likely to finish and read it to the end before starting another. If a book truly is not worth finishing, close it deliberately rather than leaving it open forever. One finished thing gives you something to think with.
