If you look under the Self-Help heading on Amazon, you'll find roughly 5,000 books listed under the subhead Self-Esteem. The vast majority of these books aim to not only tell you why your self-esteem might be low, but to show you how to get your hands on some more of it. It's a thriving business because self-esteem is, at least in Western cultures, considered the bedrock of individual success. You can't possibly get ahead in life, the logic goes, unless you believe you are perfectly awesome.
