Do you want to learn calligraphy or not?

First of all, your position on calligraphy is very vague. If you just do it as an interest, you don't have to sign up for a training class or spend money, because if you just do it as an interest, it is not proportional to the production ratio. You can't compete for the market by your hobbies.

Secondly, if you really want to make money by calligraphy, although you are 25 years old, it is not too late. Actually, it's just a matter of time investment. If you are 18 years old, you may only need to invest for one year to reach the current level of three years. Then the problem is coming. I want to take a professional way to make money. What are you going to support yourself by taking this road? You are already in grade three. What you need is a stable job and income, not trying new things.

Moreover, in fact, calligraphy and street dance are the same. If you only cultivate as an interest and lack economic ability, you can dabble in it a little, which can only be used as some unremarkable bonus items in daily life. It may improve others' impression of you when you are looking for a girlfriend or interviewing for a job, or more importantly, you can practice a different attitude and experience.

If you really want to make money by calligraphy, please consider whether you have enough economic ability and time cost to pave the way for yourself. If not, it is ok to cultivate as a hobby, but there is no need to invest money (considering that you don't want to use your own money to show that the economic level has not reached an ideal state).

Hope to accept by reference.
