A Friend of mine took a poll of the people who over think their situations or opportunities and those who jump in. After looking at the question/poll I ended up with this answer.
When we think about the things we want over and over and over it is our brain making the decision, Even though it might be a physical event or situation we still need to connect to our True Selves and and feel the right thing at the right moment. Living in the moment means living through our True Selves and we can’t go wrong with that. Even though it might not work out the way we want it is the experience and the truth that we get out of it that makes the journey all the better.
