Following traditions can be fulfilling, giving one a sense of belonging, etc. But I think no one should do so just because “it’s the right thing to do”.
If you think of it, a tradition in and of itself was originally created by an individual, or most often a group there of, by departing from what their own ancestors did, which is what we celebrate in the end. In other words, someone choosing to break away from their own might be closer to the tradition’s own creators’ mindset than those blindly following them.
Of course, traditions also often endure because they were the better thing to do and remained so for a certain length. They’re in no way valueless, and should be considered by design. But one has to keep in mind that times change, and traditions are meant to do the same along with it.
