He got on badly, being very active (2,3,2)
I believe the answer is:
on the go
'very active' is the definition.
(I've seen this before)
'he got on badly' is the wordplay.
'badly' indicates anagramming the letters (letters in the wrong order).
'he'+'got'+'on'='hegoton'
'hegoton' with letters rearranged gives 'ON THE GO'.
'being' is the link.
(Other definitions for on the go that I've seen before include "Busy and active" , "Busily active" , "Always busy" , "Ever busy" , "Active, in constant motion" .)
