Is graphic design very demanding?

I think what is more important to design is creative inspiration and aesthetic level requirements. In fact, software operation is only a basic technical ability. So the design of this post is actually the same as the copywriting post I made. I have a good background, so it's really difficult to change careers. I am also a copywriter who changed careers. I feel very tired and my ability is not good. Moreover, the older I get, the better this creative job really feels, and the less inspired my thoughts are. I just hate going into the wrong business. Alas! I want to change careers, and the company won't give me a chance. User in job q: anonymous user.
