Wow, what a coincidence! I don't like guacamole either, I don't even like the avocados from which it's made. I won't eat that vile, putrid substance. By the way, before the naysayers attack, I have tried it and I know I don't like it.
As for trying anything once, nope. The word "anything" is too broad; not all things in life need to be experienced in order for a person knows he or she doesn't like them. ~
(in Chinese philosophy), the Tao is the absolute principle underlying the universe, combining within itself the principles of yin and yang and signifying the way, or code of behavior, that is in harmony with the natural order. The interpretation of Tao in the Tao-te-Ching developed into the philosophical religion of Taoism.
I had been aware of that for a number of years and happened one day to drive past a store called Tao. I was fascinated that someone would name a store that way and I stopped to see what the concept might be.
It was an interesting store with various and diverse objects, but I saw no obvious connection with Chinese philosophy.
I bought something that intrigued me, and started talking with the owner about how she came to name the store.
Her reply---"Well, Tao stands for 'try anything once,' so we just used the letters of that phrase for the name.
