The Great Secret of Life is the Law of Attraction

“The law of attraction says like attracks like, so when you think a thought, you are also attracting like thoughts to you.
Thoughts are magnetic, and thoughts have a frequency. As you think thoughts, they are sent out into the Universe, and they magnetically attract all like things that are on the same frequency. Everything sent out returns to the source—you.
If you want to change anything in your life, change the frequency by changing your thoughts.
Your current thoughts are creating your future life. What you think about the most or focus on the most will appear as your life.”
