Short idea (95): Every experience has a "tail," which is to say that a piece of every experience lingers on after the experience is over. For example, the experience of being in a severe thunder storm lingers after the storm is gone. The alertness, the feelings of fear and/or awe, etc. Tails can last a few seconds, a few minutes, a few hours, days, weeks, months, years, and even for a whole life-time. As you get older you accumulate more and more of these permanent tails, and all new experiences you have are filtered through them. The thicker the web of old tails, the less of each new experience will get through, and, gradually, new experiences will all come to feel pretty much the same, have the same flavor, as it were. Experience will become stale.

Short idea (157): You can't trust anyone completely or count on anyone completely — not even yourself. This can be a hard fact to swallow and adjust to.

Short idea (165): Two Provisional (and condensed) Definitions: 1) Humility = Self-Knowledge + Knowledge of the Future. 2) Arrogance = Ignorance. Axiom: The more self-knowledge you have and the more knowledge of the future you have, the greater humility you have.
