We might think that we won't be able to do or accomplish something. But seeing that someone else can do it tells us, "If this person can accomplish that, I will be able to do it also."

The Sages (Pirkei Avos 4:1) define a wise person as someone who learns from every person. Develop the habit of interviewing people you meet to find out exactly how they learned to do what you would like to learn to do. What are the thoughts that go through their mind? What are the actions they take? What are their attitudes and mindsets? What are the mental pictures they see? What are the books they read? What are the classes and recordings they heard?
