Giovanni is not simply an achiever, he is the ultimate of all the achievements, the goal of every human being.
One day it comes to our house a little boy, all well dressed with a suit, wearing a pink tie. Full of elegance, he said "My name is Giovanni, I am 2 years old"
Surprised, as we lived 10 miles from town, I asked "What are you doing here? Where is your parents?"
"I don't know, you have to adopt me"
And there we are, Giovanni, sometimes referred as Jovanni, comes to live with us. For my wife it was love at first sight. Me, I knew something was fishy. How  happens that a 2 years old boy wonders around by himself, dressed like a business executive? How can he talk like an Oxford graduare? I never found an answer to my questions and over time, Giovanni proved able to amaze me more than once.
At first, it was nice to have Giovanni in the house. He was very polite and distinguished, my wife and my kids loved him. In particular, he became very close to Marco Junior. The two were getting along, driving their cars around, getting involved in their little crimes, and so on.
You may think I am an unconsidered parent, but the truth of the matter is, I never wanted to have kids. I just can't stand little children and their irritating screams. My kids were born out of my mind, against my will, and I let them do what they wanted.
Soon, the honeymoon between Giovanni and my family came to an end. My wife was working on a project, an invention with the potential to make us very rich. Giovanni found out what she was doing, stole the idea and patented on his own name. To distract us, he created a diversion, he sabotaged our car, so that Marco Junior and his sister had an accident and got lost in the wood. Giovanni and us literally entered into a war  which lasted several weeks. Fortunately, nobody got hurt, and eventually we came to a compromise. Giovanni would keep his patent, with the commitment to take care of our financial needs for the rest of our lives. After all, he said, you are my family, I love you and will never forget what you have done for me.
Despite the better financial situation, our problems were not over. Giovanni insisted on living with us. A lot of money, and no restraints, made his megalomania very evident. He hired Marco Junior, and made him driving around his luxury cars. He bought the house in which we lived, and every time we were going somewhere, he made sure to arrange thing so it was staying with us. When we decided to move to my native town in Italy, he bought all the real estate in the area, to make sure we were under his control. It was hard for all of us, but I think Marco Junior was the one who pay the highest tool. He's a loyal person, and he is always following his friend in every crazy endeavors. Giovanni eventually got tired of bothering us, and pursued a larger scale dream – to bother the entire world. I will talk later about the church he founded, his personal army and other adventures.
So believe me, Giovanni is a true achiever. He achieved his goal to annoy me and my family. Soon or later, he may annoy yours too. One day, he will knock on your door and say “My name is Giovanni, I am 2 years old. I am rich and I do what I want”.
There is no obstacle his fierce will (and his wealth) can not overcome.
However, despite all the bothering I had to endure, and the annoyance of his megalomania, I like Giovanni. I actually feel sorry for him at times. He's just a little kid, grown up without real parents, and therefore always seeking the attention he never got.
