Good question! George Bernard Shaw, the famous English author said, "People are always blaming their circumstances for what they are, I don't believe in circumstances. The people who get on in this world are the people who get up and look for the circumstances they want and if they can't find them, make them!" So how do you make your circumstances what you want? Quantum physics experiments have shown us that we affect our surroundings. (See Gregg Braden's work or Nassim Harramein) One of the main ways is through our vibration - that is the emotions and feelings that you hold in your body. Hold good emotions - joy, happiness, gratitude, love - and your vibration is high and positive. Hold bad emotions - boredom, anger, fear, hate - and your vibration is low and negative. There is a continuum of the emotions of course. Like attracts like. Positive emotions attract positive experiences. Negative emotions attract more negative. The choice is yours.
When you are experiencing the synchronicity in your life, you are in the positive vibration. So think positive!
