Too much choice?

How do we know when we have found what were looking for when were not 100% sure of what it is we want?

Were surrounded by choices in life, never have we had so much choice yet is choice really all its cracked up to be?
How can we make the right choice when there so many options?

There are  books out here who tell us if you think about things enough you will get it, I own the book I've read all the pages but how can it help when I don't know what I truly want? Or more to the point what do you do when what you want today changes tomorrow?

Yesterday I was wanting to be a successful business woman, a wife and mother spending my days between looking after the kids and working doing what I love with a man I love today well that's another story.
