Full Idea
This 'you' for which you show such a lively interest is, so far as it is not overt behaviour, at least a drive in your own peculiar nature.
Gist of Idea
The self is, apart from outward behaviour, a drive in your nature

A Reaction
I assume this use of 'drive' is the origin of Nietzsche's picture of such things, focused on the basic will to power. I like Fichte's emphasis on active forces as the basis of nature.
