You are long past the point of worrying about a decision. That's because you have already made it. At this juncture, dwelling on fears about it or second-guessing the choice you made would be silly and, truth be told, quite pointless. You thought about your options. You considered each one. Perhaps you did some research, or you asked other people for advice. And then you made your choice. Now your role is to believe in what you decided to do. Invest your faith in it. Believing can be very powerful.
