Thought.

I recently heard the phrase, the meaning of which was reduced to the following: It is impossible to tell “Yes” future, until you say “No” past. For sure, I've already read something like this somewhere, but then the thought caught on, wrote the expression on paper, read it several times. Really, how simple everything is. How can you hang new clothes in the closet?, if it is full of old? You can act decisively, and take the entire wardrobe out of the house at once. But this is a radical change, require emotional and material costs. Can be replaced gradually, changing one or two things. This path is consistent, not too expensive, but long. Or you can change nothing, keep walking in the old, worn out, but in such comfortable clothes.
