Writer’s pleasure: this writer’s off to tour Lake District initially (7,7)

'district initially' is the definition.
The definition suggests an adjective which matches the answer.

'writer's pleasure this writer's off to tour lake' is the wordplay.
I cannot quite see how this works, but
'writer's' could be 'iam' ('I am' refers to the person writing) and 'iam' is found in the answer.
'pleasure' could be 'will' (at will means at one's pleasure) and 'will' is present in the answer.
'tour' could be 'go' (synonyms) and 'go' is present in the answer.
'lake' could be 'l' (geographical abbreviation) and 'l' is found in the answer.
'writer' could be 'i' (the person who is writing these clues) and 'i' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
