Learning to draw is something anyone can do and is incredibly rewarding. It activates a huge part of your brain (visual) that starts firing when you see all sorts of scenes, faces, patterns, colors in real life. Try the book "drawing on the right side of the brain". Another good one is the Bargue sculpture drawing course.
Any artist that draws from imagination will tell you to draw from real life. Once you get that down it's waaaay easier since you have strong foundations in figures, perspective and forms. No one just started drawing from imagination.
