I've read through these posts and I think I can sum it up in quite a short post.

You don't make your wife submissive. She is submissive already, (if she is). It's all her. The trick is for you to be somebody that she would want to submit to. But she married you, so that's a strong indicator that you're doing all right.

What you need to do is figure out ow to validate her needs while at the same time remaining you. It's both your and her needs that need to be validated by each other. Certain things about you turn her on...do more of that and she'll be more submissive. Some things you do, annoy her and turn her off...do less of that since it'll make her confused about submitting. What is which...ask her. Communicate. If she doesn't tell you straight out, then listen for the clues and work it out. Beginners can rarely put words on their emotions, so it isn't fair to demand it.

Did I get it right?
