You can do whatever you want to. You can eat dessert first, you can play music and read, or you can simply do nothing and still feel happy. When you're alone, it's up to you to utilize that 'me time' in whichever way you want.
After all, it's fun at times spending time with just yourself. There's no better way to exercise your freedom of choice. Even desserts before the main course are possible!
