Praise, like gold and diamonds, owes its value only to its scarcity. It becomes cheap as it becomes vulgar, and will no longer raise expectation or animate enterprise.

Praise handed out constantly stops meaning anything, including to the person receiving it. If everything is excellent then nothing is, and the people you most want to encourage learn to discount whatever you say. Spent carefully, the same words carry weight for years. The cost of generous approval is that you lose the ability to signal when something is genuinely good.

Try being specific instead of frequent. Rather than saying well done again, name the exact thing that was hard and what the person did about it. That kind of praise is scarce because it takes attention, which is precisely why it lands.
