Nothing is consistent, the force of evolution will eventually make everything change. Nowadays things are moving more rapidly than ever and new business come and business go in a rapid manner. However that is maybe not for the majority of the companies today but for a small fraction of them. Even if he nowadays is a multi-million dollar business man, Dylan wrote this lyrics back in the 1960's. With no intention of being quoted in a business blog.
However it fit the modern times of how I see things moving around in business and should act as a heads-up for traditional business owners out there. "...start swimmin'" reflects action "...sink like a stone..." reflects consequence of action not taken.
So many business leaders in traditional organisations have not taken action/started swimmin' and are already sinking as a consequence. Primarily because they have missed out on an even more pro-active action - how have new businesses transformed their domains forever.
