Nostalgia is not a good strategy
What might have been appropriate back then, is no longer of relevance now.
When faced with uncertainty and challenges that are seemingly impossible to make sense of, there is a temptation to respond by simply calling for a going back to basics.
To return to the safety of a simpler time, a moment in history when things were more manageable and made more sense.
It's not difficult to find well-paid CEOs of very large, complex organisations (who BTW are effectively tasked to lead their businesses into better futures) calling for a 'back to basics' strategy.
But nostalgia is not very a good strategy - the reason being that what might have been appropriate back then, is no longer of relevance now.
The context in which an organisation operates today (as well as the degree of complexity within the organisation itself) is very different to what it was when it was operating basically.
In reality you cannot return a complex system to simplicity, and then expect it to perform optimally. It's impossible.
Wishing that the clock could be turned back is pointless; the only path is forward.
Instead of reminiscing on what was, rather spend the energy on envisioning what could be.
Project the mind towards the horizon and avoid the temptation to retreat to the known.
