I asked my girlfriend for her input. Verbatim:
"I love what it does for him and for us. I love to see him light up every time new plants come in the mail, we make romantic dates out of going to specialty fish stores, and I love that he is able to bring a brightness and personal uniqueness to our lovely home together. Are there specific tactics? - No. And sure, sometimes, as girlfriends, we get hours of getting no attention while they tool around, but all in all, it's the most wonderful thing seeing the one you love expressing themselves creatively and, all in all, being truly excited about life."
Not sure if that's helpful, but at least it's perspective.
