Direct ambition (3)
I believe the answer is:
aim
I believe this clue is a double definition.
'direct' is the first definition.
('aim' can be a synonym of 'direct')
'ambition' is the second definition.
(I've seen this before)
(Other definitions for aim that I've seen before include "This is mean" , "Point towards a target, or have ambition" , "Plan" , "anticipated" , "Point (a camera)" .)
