It is great to review here one of the most important teachings of my youth. This that is here published, reinforced by the act of to draw the line in his hand, gave me the feeling of power to achieve my aims even when my astrologist advised my father that mathematics would drive me crazy, travelings would made me die, etc. A long list of impossibilities that could collapse all my life if I did had not the parents I had and, above at all, the History of this so great man.
In this way, I used this History also to my seven child and I am applying-teaching this today to my fourteen grandchildren. This History is very important as an example that we must accept the advises of the others but be very careful when the advises can mix with preconceptions of that beings like my astrologist.
