Let's learn, what is the most valuable life experience of Leo?

Leo is never a submissive person. What's wrong with him? He cried louder than anyone else. They don't like to complain, but Leo can't stand unreasonable things. It is this character that makes Leo never suffer, and all the resources he should get can be obtained. Leo has goals in career and principles in life, just as they pursue their own goals. Leo will never violate his principles, which is their bottom line. Leo doesn't even think about things he shouldn't do, because once his principles are destroyed, it means that he can't go back in the future and will embark on a road of eternal ruin.
