Personal Training

Personal Training reflects on the discourse of self-optimization.
Naturally there is a human urge to strive for improvement. Everyone would like to be the best possible version of oneself.
But who defines what is good, and a worthy goal to strive for? Are one’s own sensations and desires, the “self”, really the decisive indications?
How could this “self” ever be separable of one’s living surroundings, of social norms and requirements? Can it be distinguished from capitalist economy’s demand for efficiency and productivity that we are entangled with?
