I am a really big fan of well thought out, logical arguments. Two writers whose work I really admire are Andrew Tobias and Bob Lewis. They write on different subjects in general, but I am a big fan of them both.
I first learned about Andrew Tobias through his book "The Only Investment Guide You'll Ever Need." That was back in the mid-80s. After a decade of stagflation, shady commodities deals, and my first experience in the job market, Tobias shed a lot of light on my view of the economic and financial world. Much or most of what he wrote in the book was simple common sense, but there's a lot of it, and if nothing else, it will validate your financial astuteness. His insights to markets are still valid 25 years later.
The other writer, Bob Lewis, writes for InfoWorld magazine and has his own IT consulting service. His main topics are directly related to IT workers and executives, but the lessons apply equal well to almost any other field. is columns have given me powerful insights to career and project issues.
