Marketing Sales Books Entrepreneurs Learning
The last book I read was Rob Walling's Start Small, Stay Small.
The last book I read (not counting those I'm in the middle of) was Making Things Happen by Scott Berkun. It was a great book on project management, which I think is important to anyone trying to run a business. The downside to it is that if you aren't involved in programming, then much of the book is too industry specific.
Delivering Happiness by Tony Hsieh, CEO of Zappos.com. It's wonderful, and a book about building your business through core values, from the bad days to the heydays.
Free by Chris Anderson
It tries to shed some light on the seemingly ludicrous freemium business model. I loved it.
I just finished Word of Mouth Marketing for the second time. It is filled with tons of marketing how-tos, to-dos, ideas, and examples. It puts a big emphasis on marketing to your existing customer base. Definitely worth the read.
