Has it occurred to you that we are all ACTING. Every single day of our lives? We may have a grasp of our "personalities" as is constructed and defined through living our lives, and other people may understand us as such, but WHAT IF all that we think we are is just a mechanism of control to feel safe in a predictable reality?
For instance, if I associate myself as "sweet", I act in accordance to that because then other people respond to me nicely. It's a way of controlling other people's reactions to me, because I have the experience of knowing that being "Sweet" begets a certain response.
But I am so much more than just that one quality that's come to the forefront of "who I am". We are all more than how we are defined, how we allow ourselves to be defined, and how we understand ourselves. Because we are WHOLE people.
When we let go of that subconscious control, we start to understand our real depths. We start to understand how much more is within our potential. We also start to see the full range, and appreciate that range, in other people. We can handle it because we can handle it within us.
The more we acknowledge things about ourselves, maybe qualities we've discarded, we can see how productive they truly are. Only when buried do they reveal their counterproductive sides- i.e. assertiveness can become aggression, confidence can become arrogance, etc..
