Grant points out a fascinating fact about who, among these 3 styles, is happiest and most successful: It is givers. What about those who are least successful? Also givers! Why? Givers who learn to successfully navigate a world with matchers and takers make out great. Everyone loves givers, trusts them, and supports them when they are in need. So why are Givers also the least successful? Because some givers don’t know how to navigate that world and, as a consequence, end up taken advantage of. If you’re a giver, you’ve been there at least once both professionally and personally.
