Is it really useful to keep practicing calligraphy every day?

I think it's useless. Maybe I'm too young to understand you, but I think it's no different from the copying homework assigned by the teacher at school, that is, I keep doing the same meaningless things over and over again, but people's handwriting is still the same, and there is no difference. You said that improving willpower can cultivate sentiment, improve aesthetics, cultivate the soul, read books, plant flowers, and persist in losing weight, so you can get surprises. But if you practice writing for a long time, you can only show it online. You don't need a writing brush to write documents, and you don't need regular script to catch up with manuscripts. Besides, now is the information age, and electronic manuscripts are gradually replacing paper manuscripts. After all, things that have been eliminated can only stay in museums, and people always have to move forward.
