Steve Jobs - Walter Isaacson. I thought it was interesting; an honest attempt at cataloguing the life of a fascinating and complex person.
How To Win Friends And Influence People - Dale Carnegie. I'd skimmed through it in high school, and decided it was full of obvious/cheesy platitudes, but was somehow convinced to take another look this year and I'm very glad I did. It is mostly full of very basic "don't be an ass" advice, but I needed it.
Never Eat Alone - Keith Ferrazzi. I'm not sure what to think of this one. It's pretty low on actionable advice, but it did help me (together with HTWFAIF, above) reframe the way I approach interpersonal relationships.
The Cat's Table - Michael Ondaatje. I haven't finished this one yet, but it's part of a recent concerted effort to read more fiction. I've always loved Ondaatje's work, and this latest novel is no different.
Freakonomics - Steven Levitt & Stephen Dubner. I just started reading this last night, and I'm already 100 pages in. It's an addicting read, and is already causing me to re-evaluate the incentive systems that are everywhere.
Napoleon Bonaparte - Alan Schom. I've been reading this one slowly for a while (it's a hefty book). It's a very well written account of Napoleon's entire life story--highly recommended.
Crossing the Chasm - Geoffrey Moore. Just started this one last night as well (Christmas presents!) and so far it seems like it will live up to the hype.
The Education of Millionaires - Michael Ellsberg. This one, I can't recommend. As always, though, YMMV :)
