Refusing Invitations

Do you feel guilty saying NO?

If you are someone who always feels obliged to appease people, you need to break this habit now. If it hasn't already, this habit will become a burden to you because at times, people will make requests of you that are beyond your physical or other capabilities. For instance, a friend asks you to speak at a charity function but it conflicts with your sons first championship hockey game. You should start by graciously thanking them for the invitation and acknowledge the honor of the request. It is better to be direct and tell your friend that you have other obligations rather than delaying the inevitable truth that you cannot attend. Your friend should  respect your honesty which allows them to find a new candidate or make other arrangements. You should let them know that if the circumstances were any different you would be more than happy to make help them out, especially knowing the great work that the charity does. Finally, end your refusal with a forward look and suggest that you are open to future invitations.
