This is similar to another thing that you must die in battle to make into Viking tradition heave.
Although I do not think this was maybe completely wrong. What I found was more it matched other traditions or the concept of live well… like as in the time you have do not waste it is the thing in ways.
So some may say this rushing at something saying the cause is valid so on in this way is all.
So that is just how it is maybe seen as translated. A lot of the Nordic tradition has similarities to earlier Vedic traditions just well death was more common because of harsher traditions is all.
So it is in a way similar but maybe someone took out of context in a now known or thought to be the meaning in this way.
Anyways this is just my thought
I am a fan of your not always supposed to be happy so on although this is a modern concept of something I heard… or is a thing that has mean as to accomplish things is not always and rarely is to being happy as they are being done or finished in ways. Only after if things go well is happiness maybe gain from it. You ask yourself in most cases after the happy ever after what happens in the movie is thing no one ever showed this part is the thing.
So it is odd realistic stoic type of perspective I have learned to take along my path so to speak.
I can say I am happy so far but it is not the kinda happy that I think most would understand is all ok.
