What does it mean to trust your gut?

You know when you get the knot in your gut about a decision and later you regret that decision? That is your body, your intuition telling you NOT to do what you are about to do.

Why does this happen? It is your inner guide, your higher power, God, the universe...whatever you want to call it, it is telling you to PAY ATTENTION!
