DAVID HARARI chose NOT SHOWING OFF as a trait for success:
AS A CHILD, NOW, HOW CAN YOU PRACTICE NOT SHOWING OFF?
Not showing off is a good character trait because just as Moshe was the greatest anav in the world and he was the greatest man. Also, in Pirkei Avot it says you should not show off. Clearly, if you do not show off you will be successful.
EXPLAIN HOW NOT SHOWING OFF COULD HELP YOU SUCCEED IN BUSINESS IN THE FUTURE?
If a person shows off a lot in business, people will not want to do business with him. People will think this person is a big shot and say bad things about this person.
