Again this is old, but I wanted to toss a thing in here too.

For me submission is a lot like orgasm. You'll never get there if you work too hard for it. Don't focus on what you want the outcome to be. Just relax and enjoy the sensations of here and now. Relish in every detail and drink it in. It's the small things that lead you to the fantastic conclusion! Keep your head on right now, and the ending will be all the better when it surprises you.
