Apparently, one used to be able to go to New York City and take lessons on how to "do" stand-up comedy and "improv".
One of the key enablers was to banish the words "No" and "but" from your vocabulary.
The word "No" stops the free flow of thoughts and conversations. It is a black-hole for positive energy.
The word "but" can force the conversation to bend a sharp corner and do a one-hundred-eighty degree turn. More often it hangs clutter and burdens on the train of thought. Thus burdened, the little-engine-that-could stalls out or gets wedged into a tunnel.
Powerful, confident people are comfortable with "Yes, and...". They are not afraid to go along with the ride. They do not feel compelled to slam on the brakes.
People with a very high need for dominance are envious of powerful, confident people. Those control freaks are the ones rely on "No" and "but". They are fearful.
Look at the Covid response if you want a concrete example.
Speech habits are difficult to break. If you find yourself relying on the words "No" or "but" (especially as the first words of your sentences" then you might want to work on substituting them with "Yes, and..."
It can be difficult to practice "Yes, and..." with somebody after they said something that you disagree with at a gut level. Maybe even 90% of what they said pushes every button in your head. And 10% did not push those buttons. You can say "Yes, and..." modify that 10% if you must to establish a common ground and move forward.
It will shape your thought processes and make you a more confident, more powerful person. You will also be happier and more energetic. All four characteristics will enrage the control-freaks and woke-scolds which is a double bonus.
