The concept of the “barbell theory” is that you embrace two extremes in life– rather than going for the boring “middle” strategy. For example Nassim Taleb says it is better to save 90% of your money in boring cash– and invest 10% in hyper-risky investments (rather than just putting it all into “medium risk” ventures). Nassim Taleb also mentions that regarding drinking, it is better to drink liberally 3 days a week (and completely abstaining the other days) rather than drinking “moderately” everyday.
I recently read a book titled: “A Perfect Mess”
in which the author promotes the benefits of randomness and messiness.
