Testo:

“I started my professional activity as a neurologist trying to bring relief to my neurotic patients.
Under the influence of an older friend and by my own efforts, I discovered some important and new facts about the unconscious in psychic life, the role of instinctual urges and so on. 
Out of these findings grew a new science, Psycho-Analysis, a part of psychology and a new method of treatment of the neuroses.
I had to pay heavily for this bit of good luck. People did not believe in my facts and thought my theories unsavoury.
Resistance was strong and unrelenting. In the end I succeeded in acquiring pupils and building up an International Psycho-Analytic Association. But this struggle is not yet over.”
