At a basic level, I can't live without oxygen, water and food.

Talking Maslow's hierarchy of needs, I guess there are new requirements that arise when the earlier ones are met, you know, fucking, love, friendship, intellectual discourse, etc.

Then we have things that are preferences, like favorite foods, fetish needs in sex, anchors of predictability and routine that make us comfortable, the feeling we get from certain combinations of external stimuli (like a good book and lounging in bed on a rainy day), belief systems that provide a sense of meaning to the world (religious, political, social or otherwise).

After all that, we also have to come to terms with the fact that we're never satisfied, and we've created an incredible amount of needless complexity by "needing" so much, and always needing more, and we sometimes have a crisis when we think about all that.

Then we die, and it doesn't matter anymore what we couldn't live without, and we don't need anything at all.

Am I overthinking this?
