What's the best and politest way to say "no" to something?

Saying no is not always easy. I usually try to express to the person why Im saying no in a gentle and tactful way. If I find it hard to explain myself I use a back up excuse..."I really appreciate you inviting me but my mom is having a special dinner that day/night and I promised I'd go" "I have a lot of things going on right noe, I don't want to take more reponsabilities tban I can handle and end up not being able to keep up. " Basically when saying know take responsability for your desicion and present it in a way that is not helpful to the other person.

I think the best way to say "no" to something it so assert yourself and honestly explain why you are saying no. Don't lie, or try and say sorry for making that decision , instead stand by your decision and don't feel guilty for doing it.

The politest way to say "no" is to simply say you will have to pass and it is not something you want/want to do.

Take a deep breath and look at the person you are going to refuse. Put yourself in their shoes, while remaining grounded in your own body. Finally, don't forget to breathe as you finally say no

There are many ways. You can say "no thank you" or "I'll pass". Just remember that you aren't forced to say yes to anything. You have the right to say no to things, so don't think that you are being mean or rude by saying no. If you say no, it simply means no, and whoever you are saying no to should be able to understand that. If they don't, try explaining to them why you need to say no. If you are asking for just simple easy ways to say no, you could also say, "I can't do that at the moment" or "I don't think so."

First, acknowledge that you realise the request is very important to them and thank them for asking you. Then say that it's a no - with or without explanation, that's up to you - and wish them the best of success.

Say "I am sorry" while nodding your head with a smile. It generally will communicate the message, but in a pleasant manner.

I always thank the person for thinking of me or giving me the opportunity, and explain as firmly and honestly as possible (without giving unnecessary detail or being offensive) why I can't agree. Personally, I try not to use the word "but," since that may flag my response as negative and an excuse. It's hard, though. If I can, I take a minute to think and give them some helpful information that might make it easier for them to communicate with me in the future or to get yeses from other people. Sometimes extending a helpful 'no' response can keep the mood light or even make it less likely the other person tries to negotiate you into helping further. Of course, I don't owe someone more than a 'no thanks' simply because they reached out to me, however I will push the conversation forward with an idea, more information or other helpfulness if I can!

I understand that you want me to say "yes" but, I think that "no" means to not to convince me at all

Sorry, but I don't feel like it. Maybe you should ask someone else? Say it nicely, but with a voice that says that you mean it.
