I would take a dictionary definition before a Google-searched one at this point but generally, I agree.
I think maybe the dictionary is best used as a tool to expand our lexicon and help us develop a better understanding of the concepts we are exposed to.
I don't like the concept of "my truth." There is the truth and then our approximation of it. The truth exists, but any individual is varyingly limited in their ability to access, perceive and express it.
"My truth" is a very new age term and I'm not a fan of that ideology at all.
