The subject of "need" came up in another post and it was suggested that I start another line of inquiry.
For me, it was always very confusing, "need" vs "preference". Need seemed to be much more urgent, much more do-or-die, whereas preference was more laissez-faire, fine if I do and ok if I don't.
Looking at a plant, "What does this plant need?" (Not having a green anything, I have assisted in the death of well over my fair share of plants) Well.... water, sunshine, soil, nice temperature. "And if you take any of these things away?" It will die.
Using "need as something without that the system will fail", what do humans need? Not much.
It's been argued, "Well, what do you need to play football?" Well, what do you need so that the system "playing football" functions. You could even say, "What do you need to play football WELL?" That leads into a whole set of "Well, what the hell does well mean?"
Does a human need love to function? Does a human need full nutritional compliments to keep from dying? Does a human need all it's limbs to function?
So where is this all going? Well, I think it speaks to the quality of human experience. If you have someone who is saying, "I need my double mocha frapachino in the morning" or you have, "I like having my double mocha frapichino in the morning" there is a qualitative difference, both externally and internally. If you are using need as in, "I will suffer such that I cannot fucntion" when talking about your frapachino, there is an awful lot of power in that frapachino and an awful lot of victim in you. You are being done to by your frapachino.
Look around your life at your "needs". It certainly is easier to motivate or put your attention on obtaining something if it is essential to your survival. If your needs are re-evaluated as "preferences", there's a whole lot more breathing room in your life. If it doesn't feel like a life-or-death struggle, what happens to your searches? For love, for the right job, for relevance, for meaning, for relationship, for anything.
If you buy into that you can sacrifice your very life for something that you believe in enough, then you don't really need anything. It's surprising how much of what we think we need for survival is programmed fear, "Without a relationship, I'm nothing." Working with hospice clients, I see a lot of, "What used to be so important, just isn't anymore." What exactly are any of us sacrificing to meet our unconscious beliefs about what we should be? How many of us are very, very accoustemed to the adreneline of the chase for our needs, "Have to get this! Have to get this!" The "thrill" of the chase for that that means continued existance as we know ourselves.
Driven by needs or dancing with preferences?
