I think you have exactly the right mindset about this. In fact, in my opinion, it's the best one to have. Having no real "expectations" will help to keep you from being dissapointed if you don't find what you're looking for, and will allow for a wonderful surprise if you do.
I am one of the blessed ones, I found a bmom with whom I've had an ever growing relationship for 15 years now. I pray you will be as blessed.
Best wishes to you as you being the rollercoaster ride of your life!
