Javier Fiz Pérez, Professor Psychology Università Europea di Roma says, “A realist sees reality, and says, “This is real.” An optimist sees his dreams, and says, “This will be real.” An optimist will meet with greater success, will attain more of his dreams, is happier, grows more, and has better relationships and greater self-esteem than a pessimist. Perhaps in other times this would not have been the case, but in the society in which we are fortunate to live, where there are abundant opportunities, the environment favours optimists. Optimists will suffer more setbacks than realists, but actually, these difficulties are enriching experiences. In the not-very-remote past, or in other societies today, perhaps the most intelligent option would be to be a pessimistic realist and avoid disappointments. However, times have changed, and in places where opportunities abound, they favour the optimist”
