Back to Tempests question asking about how or why we decided to get involved in the culture (this is how I chose to interpret the question)
I cant remember what started it, possibly when I looked into Jango Fett's backstory. However, after looking into the history of Mandalorians (in the legends), it resonated with me because much of how I already lived fit in well with the culture. For example, I'm simple, and from what read, Mandalorians are too, specifically looking at how Mandos adopt people into their family. I already lived by the words "family is more than blood" well before I knew what being a Mandalorian meant. I also hold family very dearly, and would do anything to protect them. I'm a believer in protecting and supporting family. I have a lot to say on the topic, but simply put, I already lived by over half of the Resol'nare.
he's a little bit of my interpretation:
-Education: for all the obvious reasons, I wont get into it. However in addition to acquiring knowledge, this also includes teaching your aliit whether it's about being Mandalorian, or anything else in life.
-Armor: now here's a tricky part, it wouldn't be socially acceptable. As much as I'd say I don't care what people think, and I don't in general, but beskar'gam simply isn't an option in almost any day to day setting/activity. I feel a more "covert" option is a more realistic approach: A vest that is meant to be worn under clothing, that can stop smaller bullets and knives, is more acceptable... If you're determined to wear armor. (just a brief thought on the subject)
-Self-defense: now I personally feel guns are a good thing, and I'm not going to go into it, but I support of an EDC gun and knife, even to use as a deterrent. Being able to use them with absolute proficiency is absolutely necessary. Some sayings: If you can't protect yourself, you can't protect what you hold dear. Practice makes very good, but you can always improve, and can never be perfect, so never stop training. Naturally train in hand to hand fighting too... check local laws, all this is a touchy subject...
-Tribe: I interpret this as your family as well as friends. Much of what would go here is the same as self-defense.
-Language: Mando'a. Realistically, it' more novelty than actual use, and can be interpreted as speaking the same languages your surroundings speak, I chose to start learning Mando'a too for personal use and as a hobby.
-Leader: Since there is no Mandalore, I choose to take this as the call to arms in the country you live in, when needed. Currently, I'm not in the service, however if a war starts, I'll volunteer without hesitation, since I'm still young enough. There are many other options besides military service one can help.
Being physically fit should also be seen as an obligation in my eyes, for many reasons.
And NO, rolls of fat do not count as extra armor.
None of this is as simple as it may sound. Some of it may seem baseless or like shallow thinking was behind it, but for everything besides the part about armor, there's more thought behind it than in may seem, especially about joining the military (much more to it than I'm going to write here).
This is an example of how there are ways to practically apply much of our culture.
