For some people there are aspects of themselves that were developed in childhood as coping mechanisms in order to feel comfortable or safe.
And sometimes those habits or behaviour that were developed during childhood become so familiar and comfortable to us that we carry them through into adulthood.
But the thing is how you coped at 6 might not be so useful to you 2 decades later, in fact you might find that it’s more of a hindrance.
This is why it’s important to get to know yourself and have a level of self-awareness where you can know the why behind the things that you do.
If you can identify something that is no longer working for you then you can also change it to something that does.
