How can I become a calligrapher? Is there a future?

It is human nature, but practicing for more than ten years without thinking, and writing for more than ten years will not change from quantitative change to qualitative change. You should gain something, not just the accumulation of quantity.

Also, find a calligraphy that you like, and everyone will practice his occasional parting cross-practice, which will be rewarding. When you practice one calligrapher's calligraphy realistically, you can easily practice the styles of other calligraphers.

I hope what I said above is helpful to you.
