Hierarchy of Needs

 Our Needs Fight For The Dominance in Our Lives
There many interesting tendencies young Abraham Maslow noticed while he worked with monkeys during his carrier. He noted that some need take presidence over the other, and there is a defined hierarchy between things animals feared or wanted. He supposed, humans react the same way and after many years have produced his innovative and paradigm changing work: the Hierarchy of Needs. Hunger is a strong need, but thirst is stronger; the same applies to our sexual desires and desire to be respected. One force prevails over the other and there is a precise order dictating what we will do first if we are hungry and ambitious at the same time. What a simple idea! But Maslow managed to take it to the level where the world of science have acknowledged it as law.
