We’re supposed to save 2 times our salary by age 35, or is it 25 times our expenses to retire early? We’re supposed to ignore Social Security, but also claim it at 62 to hedge against market risk. We should try to get out of debt as quickly as possible, but also paying off a mortgage early is missing out on potential market gains. There is so much “truth” out there, so many “right” answers, and many of them conflict. How to make sense of them and decide which are actually true? Start by tossing out the whole notion that financial truth exists in the first place.
