Seconded. All books by Gabriel Weinberg.

Some books you read to reflect upon or be better informed. His books instead, are likely to change the way you conduct your business, or validate correct behaviors you adopted instinctively.

Damn auto-correct. Of course it's Gerald Weinberg. I have my favorite: "Are Your Lights On?: How to Figure Out What the Problem Really is" just on my table right now :-)

Can't edit my comment anymore, so leave the correction here.

Highly appreciated book. But the author is Gerald Weinberg.
