Need for approval

Please help me develop a protocol for the workplace and socializing where I change my thinking about my “dire need” to be seen as brilliant and my need for others approval (as a child with trauma). I want to get rid of this once and for all.
There are very analytical and judgmental people in my field, and that’s OK. I want to be able to express my ideas and be willing to be wrong publicly. I want to be willing to not be the smartest guy in the room. I want to be able to handle disapproval. I want to develop an understanding with myself of what it means to succeed on my own terms. I want boatloads of courage. I want to win my own approval and feel good at the end of the day for what I’ve accomplished
