Only where there is struggle is there progress. I don’t mean struggle in the battle type sense, I mean the struggle between order and chaos, status quo and innovation, all info known and no info known.
Natural selection, the internet, your business, the universe… the edge of chaos is where there is something instead of nothing. Nothing is almost equivalent to no interesting thing (complete order) and no understandible thing (complete chaos). The stuff of life is in the middle!
I like to talk about happy accidents… those seridipitis tangets that one happens into if they venture into struggle and keep their senses open and opprtunistic. These branches of opportunity only come about when there’s a clash between the wellknown and the unknown.
Be mindful of history but venture forth into uncertainty. Struggle to find the edge and don’t fall off.

I just stumbled accross your blog posting and struck by the content of this post. I not exactly sure why it captured me so. I think it shows a depth of understanding of life as I see it. Made me think about important things and I like that, thanks.
I guess ‘comfort zones’ ought to be avoided… the opioid of the our links to relationships between us and the other reality.
There is nothing the body responds well to that is repetitive; not food, noise, music, people, drugs, light, dark…nothing. It always habituates until there is a change in the sensory mix that makes something short of chaos in the mix more salient.
While the call for embracing ‘happy accidents’ is attractive, it is only an accident if you are unaware of the antecedents and context at the time. That is a big set!
I would posit, as others have, we don’t know what we know and we don’t know what we don’t know. Furthermore, we know we don’t know what we know and don’t know. That is a good thing for it portends that our happy accidents will always take place independent of them making us happy or not.
