“A good person is invincible, for they don’t rush into contests in which they aren’t the strongest. If you want their property, take it – take also their staff, profession, and body. But you will never compel what they set out for, nor trap them in what they would avoid. For the only contest the good person enters is that of their own reasoned choice. How can such a person not be invincible?”
Epictetus, Discourses.

How strong is your reasoned choice? Take the time to refine what your values are and identify the likely threats (temptations, urges, distractions) that can test your strength. And when the time comes, you’ll be ready for the contest.
