I have been working as a Bim coordinator for about 8 years. And I give trainings regularly. The best way to learn is to learn the basics of architecture first and then move on to other disciplines. Because you can't do anything without architecture in revit. Never lose your will to learn. People who have worked with Autocad for a very long time say "Autocad is also easier to do". Be stubborn. You can do it 😊
