You change your attitude when you turn over this (1,3,4)
I believe the answer is:
a new leaf
'you change your attitude when you' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'turn over this' is the wordplay.
I cannot really understand how this works, but
'turn' could be 'leaf' (leafing is a kind of turning) and 'leaf' is located in the answer.
The remaining letters 'anew' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
I've seen this clue in The Hindu.
Want a hint initially instead of a full solution?
