There are endless AI art tutorials online, but the biggest trap for beginners is just binge-watching one tutorial after another. You can watch ten videos about samplers and still not know how to get the image you want. From my experience teaching people, learning by project is way faster than learning by topic.
Don’t bother systematically studying every parameter. Instead, set a specific goal—like “I want to generate a set of avatars with a consistent style” or “I need three scene images for my novel.” To achieve that goal, you’ll naturally figure out how to lock in a style, maintain consistency, and what value to set for the denoising strength.
Everything you learn is immediately useful, so it sticks. Once you finish a project, go back and watch those tutorials—suddenly everything clicks. Learning with a problem in mind is way more effective than hoarding knowledge.
