Before sitting down to write a rough draft of your resume, spend some time brainstorming a list of times when fortitude stood at the center of your experience. Whether you directly mention these instances or not, the act of starting from a place of strength will end up informing the entirety of your resume.
Prudence can be used in much the same way. Unfortunately, the idea of actually being prudent took quite a hit thanks to Dana Carvey a few years back. Those of a certain generation will never forget Carvey parodying George H. Bush, saying that "it wouldn't be prudent at this juncture..." But what gets lost in the humor is that prudence plays a large role in all of our lives, whether we happen to be the president or the local taxi driver. You just need to make sure you include this concept on your resume.
It is not as if you are working hard to create a resume that screams, "I am a virtuous and to-be-trusted person!" What you want to do is look through your own personal experiences and see if you can frame them in a certain way. Here is our everyman definition of prudence: The ability to judge between actions with regard to proper actions.
In other words, you gotta know when to hold 'em and know when to fold 'em.
Employers are looking for candidates who know how to take initiative and can be trusted to know when it is the right time to jump in or hold back. If you can make your resume communicate this, then you are a big step ahead of the competition.
