Thing is, people often mistake what they like to do most with the concept of "purpose".
"My purpose is singing" - > it needs to be translated into "I love singing so much that I'm completely blinded to other possible choices about my interests".
Purpose is meaningless itself. Because once you've figured it out, there's nothing left to do, other than repeating the same activity over and over ad nauseam
Do people say that? Well, of course they do, there's so many people. And for those few, I think... well, I don't know if it's meaningless as you say. Isn't it all the meaning in the world they require, apparently? The human trait of constantly needing to one-up one's self and others is generally accepted to be a bad one, I thought. For a person to have overcome that, for however long, isn't that a thing which should be lauded, or could be? Especially for such a purpose/interest as innocuous and pleasurable as singing. We surely have no duty to have or even be open to possessing many or even multiple interests (Excepting perhaps human nature's duty to cause that happening anyway, perhaps most of the time.) so why think it meaningless to not? Again, for some, it must be all they need.
Purpose is meaningless in itself because repetition
ad nauseam? Well, one, why not stop if it gets to become so unpleasant? if a person is at that point, maybe there's many arguments to be made that it is not their purpose anymore, and/or they should seek another. Second, above I said I couldn't see a necessity to have competing interests or purposes- but of course one can have, as well. Before, I implied that I think most people do and will. People generally make their own purposes and find their own meanings, or find none at all, I thought?
The first thing you said was "Thing is, people often mistake what they like to do most with the concept of "purpose." so clearly you have an idea of what purpose really is. What is that, I'm curious, obviously. x3
