That's the general idea. In focused meditation you let yourself focus on some kind of stimulus instead of trying to completely clear out your head. It's easier. You can start doing it for five minutes at a time; shorter is better when you're not used to it.

What I want you to do is to get yourself comfortable, close your eyes, and relax your body. Focus on your breathing. Don't think about it, just experience it. If your mind starts to wander, just bring it back in.
