Can you explain this? I think you mean that interest is something each of us creates and then seeks out - or am I missing it entirely?
Some things are inherently motivating (a more definable term for interest). The opposite gender, the smell of baking bread, certain combinations of light, shadow and color (e.g
@dave.gt 's etherial plant photo above, Turner's "
The Fighting Temeraire"). We are wired to enjoy these. Other things have to become interesting. Whether you enjoy antique fountain pens (me), first gen Leicas or Pokemon - no one is born with an interest in those things. We become interested
because we need to be interested. Hobbies like photography help us to create interests and then expand them as our experience grows. Thus, any image can become interesting - even if it was boring last year. If that is what you mean, we agree fully.
