Reid Hoffman has been an incredibly successful Web 2.0 investor and the founder of LinkedIn, and so I was interested in reading his book when it came out. The Start-Up of You is actually not about entrepreneurship but about managing your own career using the principles of entrepreneurship. I think that was an interesting perspective, and the book contained many valuable lessons.
As an entrepreneur though, I was more interested in hearing about his advice for entrepreneurs, not traditional job seekers, and the book didn't have much advice along those lines. What it did have, though, were little anecdotes and details about how Reid uses his network to vet entrepreneurs (when he wears his VC/investor hat) as well as his own career path to becoming the founder of LinkedIn, and those details I found very interesting.
Reid also recently gave a TED talk on these concepts; hopefully it will be posted soon.
The book at times seemed cheesy with concepts like "I to the We" and "Invest in yourself." I also thought the book was too LinkedIn-centric and felt that many of its lessons passively persuaded the reader to use LinkedIn more. I was able to not pay much attention to these things and focused more on the stories and details in the book that I found interesting.
My full notes are below.
Ch. 1: All humans are entrepreneurs
Ch. 2: Develop a competitive advantage
Ch. 5: Pursue breakout opportunities
