Start Being Honest and Authentic

You should no longer choose to let other people shape your personality. Be honest with yourself and have the courage to do the same around other people. Drop negative and fake personas like passive-aggressiveness, half truths excessive sarcasm. It's about you and how you can better yourself. Use people that you are around as feedback for the progress you are making. Watch for respect levels and people who change around you positively and negatively.
