If you drop a frog into hot water, the frog will get burned and jump out.
But if you put the frog into cold water, and then increase the temperature gradually, it will get cooked to death.
Beware of the small changes happening around you. Most people react to sudden changes, even if they don’t carry much importance in the long term. The sympathetic nervous system perceives the shock as a potential danger, and triggers the fight or flight response.
The slow sinking ship may be just as dangerous. Draw the line in advance, not when it’s too late.
