By immediate environment we mean parents, cultures, traditions, ethnic history, religion, school, friends, working systems, etc., but not heredity. Although several studies have been made about this topic, we are interested  to have a fresh look and present a quantitative approach on this important topic.

To start with, we recommend the following  books:

1. The Bible

2. On the Origin of Species. By C. Darwin

3 The Republic. By PLATO

4. The 7 Habits of Highly Effective People. By Stephen R. Covey

5. Sapiens. By Y. Harari
