Starry-eyed cox I quit developing (8)
I believe the answer is:
quixotic
'starry-eyed' is the definition.
(thesaurus)
'cox i quit developing' is the wordplay.
'developing' indicates anagramming the letters.
'cox'+'i'+'quit'='coxiquit'
'coxiquit' anagrammed gives 'QUIXOTIC'.
(Other definitions for quixotic that I've seen before include "Unworldly" , "Fancifully impractical" , "Absurdly impractical" , "Chivalrous and romantic like Cervantes' Don" , "Like a Cervantes character" .)
