Exercise: Mark Ripptoe - Starting Strength, Art De Vany - Evolutionary Fitness, Robb Wolf (former Crossfit guru), Erwin LeCorre - MovNat, Mark Sisson - Primal Blueprint, Randy Roach, and there are other good ones. Find the program that suits you best or mix and match. These guys tend to focus on the old-fashioned basics and employ principles of evolutionary biology. Also for strength building, Richard Nikoley recently blogged on his amazing success with the Leangains program, which seems similar to Starting Strength. It adds a carb refeed tweak that reminds me of what I've read by De Vany on taking advantage of the stochasticity of nature (including human biology), though some in the Paleo community question how much difference refeeds really make. Everyone's different, so you'll need to find what works for you, of course.
Wealth creation and preservation, finance, economics, statistics, philosophy, etc.: Nassim Taleb, Warren Buffett (even if Nassim's right and Buffett was just "lucky" financially, Buffett offers good advice on lots of subjects), George Soros (a bit esoteric and speculative, but interesting views on finance/investing), Art De Vany again (though his financial/statistical experience was more narrowly focused than Taleb's and Buffett's, so I would start with Nassim)
