What blogs and books with the potential to have a noticeable impact on a small business' success do you recommend ?
PS: This is not about creating a "complete" list - time is scarce: quality over quantity!
On reflection, the books I got the most out of that actually shaped my behaviour are...
THE PERSONAL MBA, JOSH KAUFMAN
Was blown away by this. Couldn't believe how much stuff I didn't know about. It covers everything you've asked about and more...
It's also written a bit like a Software Patterns/Recipes book, which I love.
I've read the MBA book about 5 times.
PITCH ANYTHING, OREN KLAFF
You'll hate reading it. It will make you cringe. It's uncomfortable.
But it changed my attitude to business, my products, and deals a LOT. Which is REALLY important.
Applying some of these techniques had amazing results in any dealings with 3rd parties (sales, partnerships, deals). That's because I'm a softie engineer, not a battle-hardened business man. I still read this before attending any significant meeting.
HOW TO BE THE LUCKIEST PERSON ALIVE, JAMES ALTUCHER
Covers everything in one way or another...
I keep coming back to the epic rule list in this book. I keep ignoring them in business, then learning the hard way that the list is right. He shares his failures and successes in a humerous way.
It's a real down-to-earth, eye opening book.
I'm reading Lean Startup, and have read Made to Stick, Letting go of the words, Ignore Everybody, Spin Selling, and tons more. All good books, but the 3 above were the biggest impact for me on all levels.
Obvious starting points are http://www.kalzumeus.com/start-here-if-youre-new/ and http://www.kalzumeus.com/greatest-hits/
I'd definitely suggest signing up for his Email list too at the top of that site.
Also, Made to Stick: Why Some Ideas Survive and Others Die, by Chip and Dan Heath. This helped create more effective and compelling content. It's very high-level though.
