I had a good day.
On a good day, everything is great. There's no self doubt, and nothing can trouble you. You feel assured. You become much calmer and you see the bright side of everything. Every single thing you do is fun. And even if you're just lazing around, doing absolutely nothing, you'll still be able to say to yourself, "I may seem like I'm not doing much, but I don't mind. I'm happy and contented."
