The Psychology of Money is a book that I think everyone in their 20s/30s should read as they develop their relationship with money (its focus is less on specific investing strategies, but more on how to be in the right headspace to build meaningful wealth in your life). I've spent quite a few years in my 20s learning more about how to make my money work for me so many of the points Housel brings up weren't necessarily "groundbreaking," but the way he presents them is powerful — and can apply to areas of life beyond just finances. I definitely experienced some quality "ah-ha" moments while tackling this one. "Saving money is the gap between your ego and your income." "...people tend to want wealth to signal to others that they should be liked and admired. But in reality, those other people often bypass admiring you, not because they don't think wealth is admirable, but because they use your wealth as a benchmark for their own desire to be liked and admired. . . If respect and admiration are your goal, be careful how you seek it. Humility, kindness, and empathy will bring you more respect than horsepower ever will." LTKGiftGuide
