Just came across this great post on the Kiva Blog. I know the feeling of both isolation, connectedness and lack of sleep!
"Entrepreneurialism can be incredibly isolating. On my worst days, it is me against the world. It's Matt versus the naysayers. It's Kiva versus the competitors. It's me against anyone who doesn't see the world as I see it. It's the biggest trap."
"Your challenge as an Entrepreneur comes in tapping into that which is transcendent, that which is infinite about a particular enterprise you might be undertaking. At the end of a day, at the end of a particular lifetime, what can you take with you?"
