Exploit really quiet, timid individual (7)

I believe the answer is:

milksop

I'm a little stuck... Click here to teach me more about this clue!

'timid individual' is the definition.
'milksop' can be an answer for 'individual' (milksop is a kind of individual). I am unsure of the 'timid' bit.

'exploit really quiet' is the wordplay.
'exploit' becomes 'milk' (to milk something is to exploit its potential).
'really' becomes 'so' (both can mean 'extremely').
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'milk'+'so'+'p'='MILKSOP'

Can you help me to learn more?

(Other definitions for milksop that I've seen before include "Feeble male" , "Unassertive male person" , "Feeble youth" , "Weed" , "Cissy, fond of a pinta?" .)
