如何拒绝别人(英语阅读)
If you are being asked for help in something which you (i) can't contribute much to (ii) don't have resources to help, let it be known they are looking at the wrong person. If possible, refer them to a lead they can follow-up on – whether it's someone you know, someone who might know someone else, or even a department. I always make it a point to offer an alternate contact so the person doesn't end up in a dead end(死胡同). This way you help steer the person in the right place.
7. "No, I can't."
The simplest and most direct way to say no. We build up too many barriers in our mind to saying no. As I shared earlier in this article, these barriers are self-created and they are not true at all. Don't think so much about saying no and just say it outright. You'll be surprised when the reception isn't half as bad as what you imagined it to be.
Learn to say no to requests that don't meet your needs, and once you do that you'll find how easy it actually is. You'll get more time for yourself, your work and things that are most important to you. I know I do and I'm happy I started doing that.
