Disagree. His rhetoric is a necessary antidote to the rhetoric of the real snake-oil salesmen who speak from an assumed position of authority and present their entrepreneurship as a matter of blind will and charisma, when in fact - as he openly says has happened to himself - the real process is much much harder. You seem not to be able to read tonal nuances: he is clearly not placing himself in a position of greater success than his readers in order to sh*t on their ideas; he is deploying a generalised "reality-check" rhetoric to try to disperse the stench of nonsense emitted by the other "entrepreneurs". For you to take it personally kinda makes me chuckle.
