Am I a writer? I become what I do..

I’ve been thinking about what it takes to become a writer lately, and it seems to me that all it takes, and this is not a small thing, is to write on a regular basis. The practice of writing is principal to the becoming, just as the practise of anything is critical to the person that we become. In a literal sense, the brain is mapped by repeated patterns of thought and behaviour. The technical term for this is neuroplasticity, and what modern brain scanning techniques show is that the more a behaviour or thought is repeated, the more the brain will physically adjust to ensure that the mechanisms for that behaviour, or pattern of thinking, become increasingly efficient.
This has implications for self-belief, because if we disrespect our right to write, or to practise that art form, we weaken the neural pathways that enable us to do that very thing. We are continually in a process of becoming, or un-becoming, something.
