I think Adrian’s suggestion about completing a course, then doing something similar is spot on. Or, if you’re going to do another course, stick with something similar. If you did the press start course, do the helmet or motorcycle course.
Eventually you’re going to want to do your own hard surface model project, or whatever it was that you studied, so that you have to plan things out yourself, and when you run into a problem you have to solve it on your own. The courses largely “solve” most of the problems for you. There may be one or two oopsies, but it’s entirely different making your own say stand up arcade system after doing the “Press Start” course than being walked through another hard surfacing course, even if it’s more complex. (Or just choosing a different console to model.)
You need to think about how to solve some of the topology and presentation issues yourself.
I think I probably spent a little too much time hopping around and am trying to get better about repeating things with my own projects.
Edit: A couple edits.
