The folks at Venture Hacks just updated their 35 slide presentation A quick and dirty guide to starting up. There's some great stuff here and it doesn't take long to click through. I recommend it for anyone interested in entrepreneurship or starting their own company.
One of the slides has the following Hugh Macleod quote. Not sure I agree or even think it's relevant to entrepreneurship but I found it provocative:
The price of being a wolf is loneliness. The price of being a sheep is boredom. Choose one or the other with great care.
