I feel like life is a lot better if people prioritize these things in the reverse order of what Winston prescribes. Look at our bureaucracies and you'll see that the people leading it have taken Winston's advice to heart -- excellent speakers, decent writers, and low quality ideas / creativity.
Although personally, I have no desire to become like the people who currently lead our society -- the most 'successful' -- so I guess I'm disagreeing more with his definition of success than his means of achieving it within the bounds he has set.
