The human being has 5 sense capabilities: hearing, smelling, tasting, touching, and seeing. How often do you exploit all 5? I don't mean use them, since you do so routinely ... I mean exploit them?
As you are walking down a street, do you actively catalog what your senses are picking up? Do you ask yourself, "what am I smelling at this very moment?" Do you ask yourself, "what am I feeling at this very moment?" Do you ask yourself, "What am I tasting at this very moment?" Not because one of the senses has been blown off the chart and you wonder, for example, where a particular smell is coming from (like a bouquet of roses). I mean do you actively, and regularly, think through each sense? In my life I've found very few people who do.
The world is full of high fidelity experiences, yet most people don't take it all in. They wander through life waiting for something to pop up on their senses radar. Over time, one becomes desensitized to the senses. You become dead to all of the normal amazing sensory elements that the world has to offer at any given moment. There is a whole universe of experience that can be had simply by being aware of each sense, at each moment.
Truly enjoy today. Enjoy your senses. The riches you may find can be invaluable.
