I will start things with a deeply held belief I have.
I believe in social karma. Everytime you meet up with an old friend it is a relationship reincarnated, and your past actions will color that meeting. Like wise your actions will color how you act toward others. People will pick up on your warmth and energy and that will want to share their life with you, even in passing.
I think that bad things we do will come back to haunt us. But sometimes bad things do happen without deserving it, and those times present opertunity to strengthen yourself and grow, and perhaps allow others to build on their good karma helping you.
I believe being a good person can get you through life.
This I believe.
