Humans are lazy by heuristic. Things are done exponentially more many times as the friction to do them decreases. Reverse is also true.


Therefore, minimize number of clicks in a software application.

  • 1 click -> 1M usage

  • 2 clicks -> 1K usage

  • 3 clicks -> 10 usage

  • 4 clicks -> no usage


(exponential relationship with usage and clicks)
