(As written in [lowercase]) To conduct conforming to the precepts of the Stoics, as [repression] of emotion and indifference to pleasure or pain.

[Dianne]

The ancient philosophy of Epictetus, [Seneca] the Younger, and [Marcus Aurelius], among others. Stoicism focuses on living a [virtuous] life, and devoting yourself fully to your task at hand, while stressing indifference to the events outside of your control. Stoicism teaches that the quality of life depends entirely on the individual, and that events can only make you persistently depressed or unhappy when you are a faggot.
Stoics experience emotion like any other person, they have just realized that it is a self-harming choice to allow emotions to effect your well-being after the initial emotional reaction has passed.
A [Stoic] is, in effect, the extreme polar opposite of an emo.
