After buying only one book in the first three months of the year, I crashed and burned with seven books in April.

I don't really regret any of them, but it's too many.
Still, if I extrapolate from the first third of the year, I'm on track for a pretty good year, although not as good as 2017 or 2018. I should, however, do better than that as seven books in one month is excessive. It's not as if I've read any yet.
