Confident self: ears reshaped (8)
I believe the answer is:
fearless
'confident' is the definition.
(I've seen this before)
'self ears reshaped' is the wordplay.
'reshaped' indicates an anagram.
'self'+'ears'='selfears'
'selfears' anagrammed gives 'FEARLESS'.
(Other definitions for fearless that I've seen before include "Not afraid" , "Oblivious of dangers or resolute in facing them" , "Unafraid" , "Intrepid" , "Confident" .)
