An interesting commentary by William Deresiewicz on solitude and leadership:
Thinking for yourself means finding yourself, finding your own reality. Here’s the other problem with Facebook and Twitter and even The New York Times. When you expose yourself to those things, especially in the constant way that people do now—older people as well as younger people—you are continuously bombarding yourself with a stream of other people’s thoughts. You are marinating yourself in the conventional wisdom. In other people’s reality: for others, not for yourself. You are creating a cacophony in which it is impossible to hear your own voice, whether it’s yourself you’re thinking about or anything else. That’s what Emerson meant when he said that “he who should inspire and lead his race must be defended from travelling with the souls of other men, from living, breathing, reading, and writing in the daily, time-worn yoke of their opinions.” Notice that he uses the word lead. Leadership means finding a new direction, not simply putting yourself at the front of the herd that’s heading toward the cliff.< the entire lecture is worth reading >
He has written about The End of Solitude before.
