“To the youngest of our revolutionaries, in particular, I recommend to be extremely demanding with themselves and to observe an iron-clad discipline. They should avoid being ambitious for power, presumptuous or boasters. They should be watchful about bureaucratic methods and mechanisms […] use science and computation without falling prey to the excessively technical and unintelligible jargon of the elitist specialists.  They should always be hunger for knowledge; and perseverance, and both physical and mental exercises should be part of their lives.”
