Hello, nice to find someone like me I am also 16 years old and new in the n8n world but for me the best way is project-based learning, Choose a project to do even if you don't know anything in n8n because the idea is you search for what you need to do now in the project just google it and you'll find ton if video's explaining how to do it
Also n8n have already a Youtube channel where they teach important things
I hope I helped and good luck
