From the safety of a solid diversified foundation,
one can always take the next step to setup a “barbell”,
if one wants to take calculated risks or even wildly speculate for potential upside.
However, the real solution* is to realize that one doesn’t actually even need such huge returns to be successful, or happy, or fulfilled. But, at that point, one is creeping well beyond pure finance and into the territory of human-psychology and religious beliefs.
* = not a solution within the scope of a purely “maximize number” financial perspective.
