I promise you that the same stuff galaxies are made of, you are. The same energy that swings planets around stars makes electrons dance in your heart. It is in you, outside you, you are it. It is beautiful. Trust in this. And you your life will be grand.
When your sense of self and happiness comes from within and isn't a roller coaster ride dependent on others or circumstances, you approach life differently. You make better choices. You draw to you the people and situations that matter. The others, they fall away.
