Every time we crave, long for something (or someone), there's a feeling spread through our body, it's a good feeling, we love it, we wish to prolong it, to feel it again and again, so what we do after we obtain this thing (or one) is find another object to yearn for, another thrill to feel.
We actually develop an addiction not to the objects but for the feeling accompanying the desire. It's like a state of constant hunger, you never get full, satisfaction is always temporary and upsets are endless.
Trying to explore these feelings I'm addicted to, I keep thinking about the gap, the difference between what I need and what I want. Basically all I need is a bowl of rice a day and one set of clothes. So why the hell do I have to insist on air-condition in my car? spending so much money that could sustain a whole family for five years in "less fortunate" parts of the world? isn't it corrupt enough to own a car? how big is the gap in this situation or do I really "need" air-condition like my car mechanic told me? what's the next step in the addiction game? a newer model, bigger, stronger..?
to only nourish the other big addiction: "I need more money".
Meanwhile, awareness is the foundation for the ability to change, to make better.

being consistent with the previous item, apartment and dog are next on the list of unnecessary but desired.
About love, I didn't forget but I think it can be defined as a necessity but also something that exists in abundance, for free.

just share and receive.
