A review of one's rashness? (7)
I believe the answer is:
follies
'a review' is the definition.
(follies is a kind of review)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for follies that I've seen before include "Idiocies" , "Ornamental buildings with no practical purpose" , "Rash actions" , "Silly acts or ornamental buildings" .)
