Our bodily functions are very closely related to our emotions, and our emotions are closely related to our thoughts. Our thoughts are the ones that eventually will be in charge of our mood, our happiness or our misery. Opinions are thoughts that create emotions.

Let me tell you what happened to me a few months ago.  

I bought a book on Amazon, It was Oprah's book "Live Your Best Life". I bought it from one of the vendors. He had impeccable reviews, he was the perfect vendor. A month after the date I should have received it, I sent him an email reminding him of my book.
Nothing, I sent him another couple of e-mails. Nothing.
I was mad and I complained to Amazon. But I didn't get a response from Amazon right away, so I went to this vendors page and I left him my review, which was something like this:

I will not buy from this vendor again, I didn't get my book and there wasn't good communication at all. I haven't heard from Amazon either so I think I may just have lost my money.

I was thinking, I will never buy from Amazon again, ever. I don´t want to deal with this kind of service anymore. So I stayed upet for a week about a book that I didn't get and nobody seemed to care.

Later on that week I got a refund from Amazon. 2 weeks later I got the book from the vendor.
I sent him an e-mail saying: "I already received my money from Amazon. I was not expecting to get the book any more. Why did it take you forever to get back to me?"

So he replied: "Sorry for the delay, my wife just got killed in a car accident and I am overwhelmed, I have 3 little children to look after. Don´t worry about the payment, it's a gift from me."

Obviously I felt awful.  I was feeling sorry for this guy who had just lost his wife. I was feeling ashamed about my review, feeling terrible that he gave me a gift when I left him a bad remark on his website.

But what about the review, I said. I dented your flawless reputation; how do I fix that?

Don´t worry about it, he said.

My first thoughts about the vendor and Amazon were something like:
I can´t believe it, both of them are such crooks, they don´t care about their customers! Fine. I will make sure everyone knows about it in the hope that people don´t get ripped off like me.

And here are my thoughts afterwards.
They are great! I got my money back and my book for free! This is outstanding service. I can tell they care about people.

I have another story for you about paradigm change.

One day I was driving in a main highway on the center lane. There wasn't traffic so I was driving at full speed just like the other cars.  Suddenly the car ahead of me changed lanes. The reason why was because there was a tire sitting in my lane. Since I had no time to change lanes because there were cars on both sides of me, I had to come to a complete stop. If you are in the center lane of a high speed highway you are not expected to stop suddenly in the middle of the traffic, unless you are completely retarded.

All the cars behind me, after seeing me stop, honked their horns, swore big words at me, showed me their fingers etc.  As I just sat there waiting to be able to change lanes without being able to move forward because of the tire. They really thought I was an incompetent driver for stopping in the middle of the road. Until they saw the tire.

If they had known that there was a tire there, they would have understood and they wouldn't have gotten upset.

In these two examples I just gave you, I want you to realize that we are more than likely get furious for things that are just "perceptions" not "reality".
The problem is that every time we get annoyed by trivialities we are hurting our body, affecting our blood pressure, creating an ulcer, lowering our immune system, only because we chose to be furious at some event that may not even be how we perceive it.

Every time you have the urge to feeling upset about someone or something remember:

If you really knew what is going on you probably wouldn't be upset.
If the drivers at the highway knew there was a tire in the middle of the road, they wouldn't get upset at the driver who stops suddenly on the road.
If we knew that probably the person who is driving at 100 miles per hour is taking a dying person to the hospital we wouldn't be so upset.

If we knew all the information the other person has, we wouldn't be upset.  Please don't get annoyed by events you don´t even have all the information about. It's not good for your health.
