The theory

"Mare del ghaccio" directly means sea ice , well because there is no word in Italian for Iceberg. 

The theory of the iceberg is that only 10% is on the surface , the other 90% is under the water; much like people. I make a consorted effort to draw my opinions from my own experience only. Don't ever think that you have the right to an opinion on someone else because to be honest , you don't know anything about anyone. You don't know anything about what anyone else has gone through , or what anyone has dealt with in their life. A very small part of ourselves in presented on the surface , you have to look under the water to find the very essence of one's being. 

"When you're struggling with something, look at all the people around you and realize that every single person you see is struggling with something, and to them, it's just as hard as what you're going through."
