What is 'IT'

No I don't mean Information Technology. So all computer experts look away now. 

The IT I'm referring to is the IT you hear people saying they're searching for. 

Many people are searching many things. Some are looking for multiple things. 

But what is IT? 

IT can be many things to many people

Could be:

Love

Friendship

Kindness

Patience

Desire

Money

Happiness

Closure

Wanting

Peace

Confidence

Passion

All things valid in the their own way, and all worthy of the title of 'IT'

But how do you define and measure these examples of IT?

How do you know when you have found enough 'IT'?
