Suppose your company pays quarterly bonus in the form of silver coins (or wines, or handbags…?).

If you have a lot of the same coins, you will not remember which coins are the company bonus, unless you record the amount of coins you receive each time.

My son get lots of rewards from trivial to big ones. If I want him to get the motivation, I need to remind him “that vacation was a reward for your effort in ..”. Otherwise naturally  he is likely to assume those “good” things are unrelated to his good or bad actions. The cause/effect is not obvious to us until we are in our teens.
