By not caring.How are you biding your time?
The DS9 books lost whatever plot momentum they once had. The long wait would be acceptable if there was actually some wrapup at the end of each book; but because of how heavily serialized the books are, it's rather difficult for someone to come back to the story after a break.
(And before Christopher brings up "but other series don't have their books so close together": they also actually tell complete stories in one volume.)
I must be reading the wrong series, as most of the series I read, the individual books *don't* tell a complete story.
