What is the difference between needs and want?

Needs are essential things that are necessary for survival, such as food, water, shelter, and clothing. Wants, on the other hand, are things that are desired but not essential for survival, such as luxury items, entertainment, or travel. Needs are things that are required for a person to live a healthy and fulfilling life, while wants are things that are nice to have but not necessary for survival.

A need is something One cannot live without and it brings severe lack in him but a want is what One`s interest is lacking.
