“You have to persevere and fortify your pertinacity until the will to good becomes a disposition to good.” ~ Seneca from Letters from a Stoic
First: let’s define “pertinacity”: it means “holding firmly to an opinion or a course of action” as in “he worked with a pertinacious resistance to interruptions.”
So, we need to work with a strong discipline until our will power to do the right thing leads to a DISPOSITION of doing the right thing. Make sense? I love that.
Seneca also says: “How much better to pursue a straight course and eventually reach that destination where the things that are pleasant and the things that are honorable finally become, for you, the same.”
And, this is a good time to remember Aristotle’s wisdom that: “We are what we repeatedly do. Excellence, then, is not an act, but a habit.”
