Steve and Dan discuss the Stoic practice of Voluntary Hardship (aka Voluntary Discomfort and Voluntary Suffering), which is physical discomfort that we choose to expose ourselves to for the purpose of improving ourselves.  Voluntary Hardship is implemented for practice in the Discipline of Desire & Aversion with a view to cultivating the Cardinal Virtues of Temperance and Courage. Examples of Voluntary Hardship include things like fasting, confining beverage consumption to water, wearing light clothing in cold weather, strenuous exercise, and foregoing other pleasures, among many others.
