Little thinker

Did you ever think your life would be the way it is now? I can say I never thought my life would turn out the way it is. I mean when I was younger I would play with my barbie’s, the way I thought my life was going to be like, such as; The huge mansion, the wonderful boyfriend (Ken of course) and the most exciting friends that are “always” there for you. Well, I can say my life is the opposite from my Barbie life. Can anyone please explain how this works out? You know exactly what you want for yourself, but then it doesn’t turn out that way. What is going on in our mind at that moment to get ourselves in that position to make us settle for less?
