Possibility of future success; view (8)
I believe the answer is:
prospect
I believe this clue is a double definition.
'possibility of future success' is the first definition.
(I've seen this before)
'view' is the second definition.
(I know that view can be written as prospect)
(Other definitions for prospect that I've seen before include "Survey the outlook" , "Possibility of future success" , "Expectation" , "Outlook - search for valuable minerals" , "Outlook, aspect" .)
