I can thoroughly feel you. The reason you think so is because you are still young, which means you have a lot of time to spend. If you reach a certain age, like in your fifties, you will definitely change your mind, and I bet you will never do those so-called "relaxing and enjoyable" things again or at least you will decline it to the minimum. Of course, it is just my assumption and it is not necessarily right. However, everyone has his own attitude towards hobbies, no matter what hobbies they have, as long as those hobbies are legal, they are all right.
