Solitude and Leadership: If you want others to follow, learn to be alone
The author's characterization of leadership sounds to me a lot like clinical depression. This isn't altogether surprising to me, as I keep stumbling upon pieces of research or philosophy suggesting that depression has an evolutionary purpose. I think the essential property is that a depressive isn't able to ignore important problems the way a normal, functional person is able to, especially long-term problems. The hitch is being able to address those problems, rather than being overwhelmed by them.
