The best time is now
One of my favorite stories is the one about the wise old man in a small village. Two young boys once approached this wise old man and asked about a bird that one of them had in their hand. They asked if the bird was alive or was dead. The wise old man knew that if he said it was alive they would simply crush the bird and kill it thus proving him wrong. If he said it was dead they would simply open their hand and release it, again proving him wrong. So his answer was this; he told the boys that the answer to their question was in their hands. Their actions would determine the answer to the question.
