*The fear of being thought, 'not good enough' is a driving force behind the majority of unhelpful and emotionally driven behaviours. These in turn can become mental health problems. A mental health problem often shows in symptoms of sub-threshold Post Traumatic Stress Disorder (PTSD), where the emotionally driven behaviour is the result of a traumatic reaction to something based in childhood. It's not just feeling 'not good enough' in the present day, it's about carrying those feelings for years, decades, perhaps even a lifetime. I have read hundreds of articles, case studies and life stories. In over 90% of them, the person reports childhood feelings of 'not being good enough', often blaming other people. These feelings can lead to unhelpful behaviours or more helpfully, the driving force behind success. I have a brilliant friend in their seventies, who has been mentally unwell for two years. Through their life, no project, whether domestic or professional was good enough, with mental exhaustion as a result. Their behaviour is emotionally driven by a fear of their father's anger at 'not being good enough', as a child. It's sad. They are not alone. On the other hand, a child growing up with feelings of 'not being good enough', can, as they mature into adulthood, develop a 'I'll show them' attitude and achieve success.
* Returning to the feelings of 'not being good enough'. If, for any reason, a child at some point in their upbringing, felt that they were 'not good enough' to get a need met, as mentioned above, their ability to manage those feelings in adulthood can result in emotional immaturity. Sometimes, it can be a perception and not the truth, but the result can be the same. Hence, some adults behaving like children. Also why some adults are 'Chasing Rainbows', in their often exhausting, damaging and pointless search to have those childhood needs met in adulthood. That was then, this is now. The past can never be changed, but the present can.
