I like this phrase because it reminds me of my grandmother, she told me, observe people, you do not have to have your own experiences to learn, learn by looking at others and if I done, I observe people and their reactions and I learn how to do it better.
(but through the world's words and reactions, I did earn them)
Smart woman. Yes, we can learn a lot by mere observation. We can save ourselves the painful experience if only we can sit down, look and observe.
