First of all it needs to be said that there are two different ways to approach this; from the definitional perspective and from the philosophical perspective. 'Stoicism' has two different meanings; it is both a way of life, a philosophy, and it has a common understanding that is used in everyday speech by ordinary folk, without reference to any famous Stoics like Marcus Aurelius.

It's the common understanding that I have in mind here, not the ancient philosophy. People think of Stoicism as a suppression of feeling, of neglecting one's mental and physical health, working oneself to death, and trying to "lift oneself up by the bootstraps" (which is, of course, an impossibility).
