There is a very famous Taoist story – I love it tremendously. The story is about
an old Taoist farmer whose horse ran away:

...That evening the neighbors gathered to commiserate with him since this was such bad luck. He said, "Maybe." The next day the horse returned, but brought with it six wild horses, and the neighbors came exclaiming at the good fortune. He said, "Maybe." And then the following day, his son tried to saddle and ride one of the wild horses, was thrown, and broke his leg. Again the neighbors came to offer their sympathy for the misfortune. He said, "Maybe." The day after that, conscription officers came to the village to seize young men for the army, but because of the broken leg the farmer's son was rejected. When the neighbors came in to say how fortunate everything had turned out, he said, "Maybe."

This is the attitude of a man who understands what is accidental and what is
essential. The accidental is always 'maybe'; it is a 'perhaps'. You cannot be
certain about it, you need not be certain about it. People who become certain
about the accidental are going to be frustrated sooner or later; their certainty is
going to create much frustration for them. Their certainty will create expectations,
and they cannot be fulfilled – because the universe is not there to fulfill your
expectations. It has its own destiny. It is moving towards its own goal. It does not
care about your private goals...
