Once a Hasidic teacher told this parable:

A man had been wandering about in a forest for several days, unable to find the way out. Finally, he saw a man approaching him in the distance. His heart was filled with joy. Now I shall surely find out which is the right way out of this forest, he thought to himself. When they neared each other, he asked the man, "Brother, will you please tell me the way out of the forest? I have been wandering about in here for several days and I am unable to find my way out." Said the other to him, “Brother, I do not know the way out either, for I, too, have been wandering about in here for many days. But this much I can tell you. Do not go the way that I have gone, for I know that it is not the way. Now come, let us search for the way out together." The teacher added: "So it is with us. The one thing that each one of us knows is that the way we have been going until now is not the way. Now come, let us join hands and look for the way together."
