Relaxed with a walk in the park before working (4-5)
I believe the answer is:
easy-going
'relaxed' is the definition.
('easy-going' can be similar in meaning to 'relaxed')
'a walk in the park before working' is the subsidiary indication.
'a walk in the park' becomes 'easy' (I've seen this before).
'before' means one lot of letters go next to another.
'working' becomes 'going' ('go' can be a synonym of 'work').
'easy'+'going'='easygoing'
'with' is the link.
(Other definitions for easy-going that I've seen before include "Calm - relaxed - nonchalant" , "Placid; over-tolerant" , "Placid and tolerant, relaxed personality" , "Placid and tolerant, not strict" , "Hairdresser's shop" .)
