There you are, you have thrown the dice - and events are out of your hands. At that point, all you can do is worry - and you need to control the worry. So figure out exactly what you are worrying about - whats the worst that can happen - and live with that. Then when events turn out better than the worst case - which will almost always be the case - you are happy and able to carry on. Otherwise you look at the hole rather than the donut.
I understand.
