Doing one’s own thing daily (11)
I believe the answer is:
independent
'daily' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for independent that I've seen before include "not involving others" , "Autonomous" , "paper" , "Self-governing - newspaper" , "Unbiased" .)
