Here is the three-step process for eliminating excessive niceness and becoming a much more authentic, confident version of you: 1. Decide to be not nice. 2. Do the not nice stuff that makes you scared and uncomfortable. 3. Work through the internal backlash (guilt, anxiety, doubt, fear) afterwards. Then do it all again. If you continue in this process, and do not stop, over time you gain more power and stop being so anxious about other people’s opinions of you.
