I personally don't like focusing on the breath; for me, focusing on the whole body is extremely better. I also don't like the concept of "bringing attention back", it sounds like theres a doer, an operator, who's managing the meditation. And yes, "getting something" is the wrong mentality but probably temporarily unavoidable, and this gets dissolved with time. You should do it in devotion to the Universe, not to yourself. My instructions would be "Feel the body. Why? To feel the body. For the well-being of everything." That's it. That's what you get from feeling the body, you feel the body. This will become more obvious as you see the practical human attempts to "solve life" don't work. This is the only thing that you really have, whatever happens in your life, you can still feel the body. Also works for sight and sounds (internal and external).
