If I have learnt one thing this trip, it's how strong our minds really are. They have complete power over our lives and our bodies. My mum always taught me that you can do anything if you put your mind to it and I have believed it ever since. Our minds really are the most powerful thing we have going for us. I'm no Scientologist but I do believe that we can control our health by controlling our minds. It's the most precious tool we have and something that nobody else can take from us if we will it. Check out 'You Can Heal Your Life' by Louise Hay. I first read this book in high school and have been using the principles on this trip to avoid getting sick. 'The Law of Attraction' is another cool one by Jerry and Ester Hicks. This was one of the first things written recently on this subject that came before the massively marketed The Secret by Rhonda Byrne.
