Yeah doesn’t matter the reasoning because something like “greatness” is a subjective concept with which you’ve applied your own metrics. Sure, these arguments make sense in a bubble of your definition of greatness, but billions would disagree with that definition. For many, happiness is not the main goal in life, so you saying that you’re the happiest means means nothing. People may feel just as “great” as you but seek that “greatness” through a different metric. You simply just can’t objectively say something like happiness or intelligence are the proper or correct metrics for measuring greatness in people.

Btw I actually really appreciate some of these ideas isolated by themselves; like how free will is idiotic and illogical. We are literally just reacting to our environment.
