I would not use the word "stuff." I wish I could think of a really great substitute but failing that I would prefer "Things that Make me Smile."
You can go on and on with lots of sayings like, rings my bell, floats my boat, etc. but I'm not one for this approach on a blog. If you can see where I'm headed, try phrases closely related, such as "Things that Lift My Spirits,"
"My favorite Things," etc. Good Luck - Nice Blog.
