Elay Amitay Halevi argues that chasing external success like money and status can't fill an internal sense of unworthiness. This void runs unconsciously in most people and explains why highly successful people often stay unhappy or depressed despite their achievements.

So this feeling of not being good enough or being unworthy, when you really break it down, it's crazy because so many people have this, and I think most people run this in the background unconsciously, and they wind up creating this whole existence, this whole personality, this whole life, just to soothe this feeling of not being good enough. So this is why you'll see people who, they end up getting a lot of success. They might make a lot of money, they might do really well in business, but they still have. Have that void. They still aren't happy. This is why super successful people, they end up depressed, they end up going off the rails. It's because the success, the external markers of success and things that might make a person seem good enough don't ever actually fill that void of internal value.
