In economics, a want is something desired having to do with, distinct from a need. It's said that people have unlimited wants, but limited supplied resources. Thus, people can't have everything they want and must look for the best alternatives sometimes that will cost them less. This may be distressing to some people and may lead to depression which can be avoided if other people can give them their original wants so long as it's not a great burden on others.
People usually carry the tendency to have a strong desire to obtain something. This desire, known as "want" has been established since the beginning of life. The first cavemen wanted to be safe so they developed weapons. Before cavemen there were dinosaurs that were hungry and needed to eat. They wanted food so badly that they would kill other dinosaurs in order to satisfy their want.
There is an often stated quote, "You always want what you can't have." It is meaning that after we have something, it is no longer a want, so we move onto the next 'want' on our list.
In Psychology, a "want" indicates an existing need.
