Too proud and useless (4)
I believe the answer is:
vain
This might be a double definition.
'too proud' is the first definition.
'vain' can be an answer for 'proud' (similar in meaning). I'm not certain of the 'too' bit.
'useless' is the second definition.
(I've seen this in another clue)
'and' is the link.
Can you help me to learn more?
(Other definitions for vain that I've seen before include "Swollen-headed" , "Conceited - or a waste of time" , "Egotistical" , "Producing no result" , "Conceited - futile" .)
