Hello! I think the 50% rule means that 50% of the time you spend drawing you just draw whatever it is you want to draw. If your dream is designing jewelery - do so! If you start following along tutorials that would probably count as focused studying, where your primary concern is learning and be included in the 50% that includes the Draw a box lessons.

To answer your question:
just sitting down and draw "something" without really knowing what Im doing?
Yes, as long as that "something" is something you want to draw!

Hope that helps!
