“Each one hopes that if he feeds the crocodile enough, the crocodile will eat him last. All of them hope that the storm will pass before their turn comes to be devoured. But I fear greatly that the storm will not pass. It will rage, and it will roar ever more loudly, ever more widely.” – Winston Churchill
Take the short-term pain, to benefit from the long-term gain.
Most of the time appeasement just delays the inevitable. The source of the appeasement is usually fear of the unknown and lack of confidence. So we give into the fear and tolerate the bad behavior.
Making decisions and having the courage to follow through frees up space and lets everyone get on with life.
