This is not specifically a martial arts post, (though many martial arts schools do describe themselves as unique), it is more of a personal rant. This, I believe, I can indulge myself in, as I am reasonably certain that the number of people who read this blog can be counted on less than the fingers of one hand.
Stop using the word unique.
It adds nothing to your conversation.
Everything is unique.
Name one thing, anything, that is not unique.
So by describing something as unique, you say nothing that is not already known and obvious. It is akin to describing a bone as bony.
Being unique is not special, or unusual, or even, unique.
So just leave the word out of your vocabulary.
