She finally received rent, a personal morale-booster (3-4)

Ross

I believe the answer is:

ego-trip

'a personal morale-booster' is the definition.
(boost for one's ego or morale)

'she finally received rent' is the wordplay.
'finally' says to take the final letters.
'received' becomes 'got' ('get' can be a synonym of 'receive').
'rent' becomes 'rip' (rent can mean a tear in something).
The last letter of 'she' is 'e'.
'e'+'got'+'rip'='EGO-TRIP'

I've seen this clue in The Telegraph.
