Progress through life in a rush (6)
I believe the answer is:
career
I believe this clue is a double definition.
'progress through life' is the first definition.
(I've seen this before)
'in a rush' is the second definition.
(career can mean to race around)
(Other definitions for career that I've seen before include "job, but one that lasts for years?" , "Life's work path" , "Business course through life" , "Gallop" , "Vocation; rush" .)
