For context, this is for a tattoo I'd like to get but I want to make sure it's syntactically correct as best as possible.
I think the phrase is a great one, however I would very much prefer it to be something along the lines of "determined", "fierce", "resolved" (etc.) instead of "lucky".
So I pose a few questions here - Would it be syntactically correct to simply replace felicem with, for example, Certus?
Any recommended words? My Latin knowledge is near enough no better than your average Joe.
If this is too complex or can't be done with a high degree of certainty, any alternative phrases with a similar connotation?
(Also. Though I like the phrase, I can't seem to find it's origin. Anyone know?)
