Like most things I'd say experience. So I come from a tech background and as a result was introduced to aid tools and workflows before chatbot went mainstream. Very quickly I realised prompt engineering is the key to really leveraging any of these tools. Be it for image or video generation, script writing etc. I spent every moment I could learning all I code about it. What are the advanced methodologies, prompt styles, construction. How do you get consistent high quality results with minimal tweaking and interference? It's a conversation and a collaboration between you and the ghost the machine lol.
