Clever being like that, you get somewhere at last (6)
I believe the answer is:
astute
'clever' is the definition.
(I've seen this before)
'like that you get somewhere at last' is the wordplay.
'like' becomes 'as'.
'at last' says to take the final letters.
The final letters of 'that you get somewhere' are 'tute'.
'as'+'tute'='ASTUTE'
'being' acts as a link.
(Other definitions for astute that I've seen before include "Canny and sagacious" , "Sharp and clever" , "intelligent" , "Clever and canny" , "Subtle" .)
