I agree with the idea. If you worry about not upsetting anyone, about appealing to and appeasing people, you only present your thoughts in a diluted form and don't dare voice certain ideas, because you know it could upset certain groups. Lukewarm, half-developed, timidly spoken thoughts don't change the world. Yet, change is needed. In that sense, fear of rejection and the attachment to the approval of others prevents you from achieving success. It makes you unsuccessful because people don't respect people-pleasers anyway, and you're so concerned about not upsetting anyone that you forget how to think. What's left of a life if you can't even have freedom in your thoughts?
