For me definitely being judgmental, critical and controlling.
I've come to realize that not only was I being judgmental, critical and controlling to those around me but I did it SO badly to myself. Everything I was inflicting on others I was inflicting on myself 10 times over.
There's a great quote that I always try to remember:
"As I see that how I treat others is a reflection of how I treat myself, I am kinder to myself in all I say and do" - unknown
It was a part of my horoscope one day and definitely one to think about.
