Conflict surges back and forth. There will be advances, and there will be reverses. It is inevitable: no one who is actively engaged in the games of life will be able to avoid reverses. But then the question becomes: how may reverses be characterized as gains?
If you believe that this is not a question worth asking, then I would disagree strongly with you. There are times when it will be necessary to conceal the magnitude of one’s reverses, so as not to embolden the enemy.
Remember: you will normally have very few allies. Most people want to see you fail, so that their inaction and timidity are thereby affirmed. We must be mindful of human nature, which in these matters resembles the proverbial crab in the bucket, clawing at every other crab, to the detriment of all.
