Your wisdom is just hindsight with a smug expression.

This quote suggests that wisdom, often revered as deep insight and sound judgement, might simply be hindsight masquerading as profound understanding. The humour lies in the irony that while we celebrate wisdom for its perceived depth, it may merely consist of obvious conclusions drawn from past experiences, now presented with self-satisfaction.

It highlights the superficial nature of so-called wisdom, implying that it can be more about projecting confidence than possessing genuine insight. Instead of providing new perspectives, wisdom might offer little more than retrospective clarity, adorned with a confident demeanour to create an illusion of depth without substantial foresight.
