Analogy

Professor Richard Feynman of Caltech, perhaps still one of the most famous names in modern science, was once asked-

"If all was destroyed and all our gathered knowledge lost, and you were able to tell the humans of that time about any one scientific principle- what would it be?"

His reply-
"It would to let people know that everything in the word is made of tiny particles called atoms, which attract each other when they are far apart, and repel each other when pushed close together."

His statement may seem simple- but from it can be derived dozens of fundamental concepts of science.

I would make an analogy to this, when it comes to understanding human behaviour. Something to always keep in mind if you want to understand how the mind works.

Humans are always drawn to what is beyond their reach, and reject what they already have.

This is fundamental to being human, there is no cure to it, nor perhaps should there be.

EDIT:
I would like to take some time to appreciate the fact that I now study in a college where Mr. Feynman himself had delivered lectures- and have been fortunate enough to attend a lecture by one of Mr Feynman's students- a Nobel Prize winner in Physics.
