The Power of Your Mind.

Yesterday, I was reading about metaphysics. The author of the book told stated that you can change any situation of your life if you want. For instance, if you have positive thinkingthoughts about any problem, you will attract positive situations. On the other hand, if you are worried about something, the energy can not cannot flow because of it your worrying. What do you think about it that? Could it be true? Please write your opinion. :)  [ja ja, tonterías]

You are writing well. You have the ability to construct complex sentences. Try to avoid using the "impersonal you".
