They say if we believe in something, there’s a chance it will come true. So, if you believe in the potential of a miracle there’s a chance that one will happen. And if you believe that nothing is ever going to work out, well… it’s not a happy attitude for a successful balanced life. Our beliefs can have both a positive and a negative effect. As substitutes for understanding they’re unhelpful. When they bring us more faith in ourselves they’re valuable.
