want vs need

I've noticed in my years on this site that there is a lesson to be learned the difference between need and want. They both are different and not the same at all. So what are the differences between the two. Are there really a difference? Yes there are! Here are the difference in my own words. 

Need: I find this word as if its begging. Or not really wanting what is true. The word is so passive. I always see it used with the newer dommes that are new to the lifestyle. I also see it as i said begging. Its like I need to pay my rent as i am a poor student. Or i need this IPhone now. and more that i've seen. need is used in a way of oh i need a hair cut badly, or i need to clean my kitchen. but when it comes to the findomme world, its entirely different usage. 

Want: This is a more powerful word in the findomme world. It shows the feel of wanting. the feel of power, etc. I find this word also the turn on for the slaves. I want tributes from my wish list now. I want you to be a good boy and serve, etc. I also find this word exhilarating. It also gives you a high that is suppose to be. 

so, need vs want. Its want never need. Want is more powerful, need isnt. Want is desirable, a pleasure, etc.
