Artist sketches endless daily struggle (3,4)
I believe the answer is:
rat race
'daily struggle' is the definition.
(I've seen this before)
'artist sketches endless' is the wordplay.
I cannot quite see how this works, but
'artist' could be 'ra' (Royal Academician, member of Royal Academy of Arts) and 'ra' is present in the answer.
The remaining letters 'trace' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for rat race that I've seen before include "Competitive routine with no time to relax" , "Struggle for necessities" , "life's futile struggle" , "Daily struggle to get on" , "unhealthy competition" .)
