Albert Einstein (1879-1955) first visited Princeton in 1921 — the year before he received the Nobel Prize.
Einstein was said to have had this sign hanging in his office at Princeton.
The sentiment is really this. You need to focus on what counts.
While it is important to measure things, there are many things, such as integrity in business that cannot actually be counted. And there are many things that are measured that aren’t really important.
In business, what gets measured, gets accomplished. And what gets rewarded, gets repeated.
Make sure to focus on the things that really count. Find a way to measure those and reward those things, so that they will get repeated.
