Knowing I have a consistent stream of cash coming in.
Paying bills (student loans included) and seeing that I have enough to treat myself with something if I choose to.
(Goes with the aforementioned) Having an off day, and having enough energy/get up and go to just do what I want to (buy books, get food I don't normally get, buy myself something I want)
Seeing my little cousin, because she's ALWAYS happy to see me. She's the little sister I never had.
Naps. I don't get them often, because it's usually a sleep session for me, but nothing like a good legit nap.
