I had a doctor tell me once to only mention something once to someone and then let it go.
The reason is that when you mention it more than once you become annoying and generally waste your time. If someone is open to something then once is all you need, and if they aren’t, then additional requests will not work.
I sometimes struggle with this. It is not easy to be told that your ideas or thoughts are not important enough to be responded to. Yet, if people don’t wish to respond to you, that is their choice and you can make your future decisions accordingly.
Generally by only saying something once things have gone better for me in my life. I no longer need to get acknowledgment from others, and if they don’t value what I think then I move on to someone who does.
Others have the freedom to not act, and so do you. Don’t waste your time and energy telling people something twice.
