I feel I’m late on the uptake coming across Timothy Ferris (of four-hour fame, not the comsmologist), the “world’s best guinea pig”. He’s tried out all sorts of stuff so that you don’t have to. Check out his books on dieting and entrepreneurship. Many of the tips seem counterintuitive, like eating sweet rolls once a week while dieting, but if you’re ready for some fresh ideas you’ll find plenty to consider.
I am thinking of preordering his newest, “The Four-Hour Cook”, which is reported to include information on how to learn anything.
