"Finally, some time!" I think to myself. But then, the question pops up...What is time? How do I like to spend it? What should I rather be doing? Am I spending my time appropriatly?  Why do I do the things I do?  And, simply put, I try to ignore all of these questions. For one moment, I just want to live, and be. I don't want the pressures of life getting in the way. I just want to do the things I like to do, and continue. Instead of constantly questioning and being concerned with  why we do the things we do, lets just sit- and enjoy them. Too often we don't do the things we love just because we can. In my opinion, you are entitled to do what you want. ( assuming it isnt starting a Genocide, or something radical like that). But, really, how often can you say you do something for the sheer enjoyment of it? Isnt there always some kind of compensation or something else tied into it? For example, look at me and school. I adore coming to school and learning. But, I am here for a bigger reason. To get a degree, so I can work, and make money, and buy food, and have a roof over my head. There are these responsibilities that go along with everything we do. Is that fair? Perhaps this is just "adulthood". Perhaps thats why so many adults are bitter and hate their lives. And maybe thats why children are so jolly and pleasant. Children who want to swing on the playground go and swing. They do it because they enjoy it. There is no thought process. It is simply " I want to swing" and not " I could swing, but it might be better for me to play in the sandbox today..."  There are no other alternative outcomes. Just to be happy, and have fun.
So maybe for you its math or reading. Maybe its playing softball, doing yoga or listening to music. whatever it is, let it be for you. And let yourself fully enjoy your time.
let yourself live. just be, and enjoy.
