I don't user nicer paper for everyday use because frankly, I go too it too much to be constantly buying more, but I do keep a couple of nice notebooks for special purposes.
1) A Moleskine notebook/journal that I fill with quotes using different nice pens. These quotes can be from famous people or just someone close to me, but they're good to look through for inspiration/motivation when I need it.
2) For similar purposes as #1, I have a Rhodia notepad where I write down all the milestones I want to achieve and have achieved in my life as a sort of "checklist."
Here are the links to the aforementioned:
Rhodia notepad (in hindsight I wish I'd bought the wirebound one, but I got mine from my university bookstore on sale along time ago).
Moleskine (you could probably get the same quality paper for cheaper btw, Moleskine is definitely nice but usually considered a tad overpriced for what it is).
