This ones for the women (although it is ABSOLUTELY applicable to some men too!).
As a psychologist, I consult with many women. Women who are successful in many different roles in their lives. They are smart, resourceful, strong, value-driven and more amazing than most of them realise. Some of these women don't celebrate, or even recognise their strengths, because their mindset is often focused on perceived "failures". Their mindset is self-critical and demeaning, self-judgmental and often unfair.
