This is the problem
Ludwig Von Mises with Praxeology explained the Universal Law of human action which is the ultimate cause of the inevitable human suffering because it is, by definition, purposeful and conscious, it is the necessity to choose, always and forever, and with it always going with a cost, a price to pay, psychologically and practical, the opportunity cost, the suffering.
Jiddu Krishnamurti is a great philosopher which devoted his whole life in understanding such ultimate cause of suffering, indeed he teached that the ultimate end of suffering is the choiseless action, which is a life of total acceptance and attention to the present.
This is the path I consciously chose to follow in my life, thank you Ludwig and Jiddu !
And you ?
