Sometimes it comes so quickly that it is almost unbelievable. When it comes you can see absolutely nothing. You cannot feel your way under those circumstances because there is nothing to touch. You can listen for sounds that will tell you what is near you and what to watch out for. So you make for the lightship because you hear the sound of its foghorn, and you may finally see, when you get near enough, the light that comes from its beacon.
Life is like that too.
There are times when the visibility is high. You know it as well as I do. There are times when you can see clearly everything that lies ahead of you. There are times when your way is plain. You know exactly what you want to be and where you want to live.
