The more sand that has escaped from the hourglass of our life, the clearer we should see through it.

Time spent does not come back, and no amount of perspective returns it. What a longer life does leave is a longer record to read from: you have watched enough things turn out to have some sense of which worries were real. That clarity is not automatic, and it does not arrive as a reward for lasting. It comes only if you look back honestly and let what happened correct what you assumed.

Think of one thing you were certain about ten years ago that turned out differently. Name what the mistake was made of, and check whether you are making the same kind of guess right now.
