Enterprising person having got egret out (2-6)
I believe the answer is:
go-getter
'enterprising person' is the definition.
(I've seen this before)
'got egret out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'got'+'egret'='gotegret'
'gotegret' anagrammed gives 'GO-GETTER'.
'having' acts as a link.
(Other definitions for go-getter that I've seen before include "Informally, an agressive achiever" , "Person who is successful through aggression and energy" , "Enterprising person" , "Someone whose career progresses rapidly" , "One who succeeds through energy and drive" .)
