Are there graphic designers here?

Sometimes I create my design for printing products in one of the graphic editors, for example Illustrator or Coral Draw. I like this work because it doesn't take much time and I can quickly create a brochure design when I use these free mockups  https://www.ls.graphics/free-mockups/brochure-mockup  . I like that on this portal there are a lot of such mockups and that there is a lot of information about what trends in graphic design and how I can make my skills in this better. I believe that you need to constantly learn something new and look for a way to automate some processes in order to become the real professional in this.
