You'd also probably go nuts.
In the interest of maintaining your sanity, it helps to learn how to selectively weed through the invitations you receive and politely say "no" - not "maybe," not "I'll get back to you (but secretly I won't)" - to the less appealing ones.
According to Rosalinda Oropeza Randall, an $4 and the author of "$4," it's all about "owning your no." That is, not giving into pleading and not feeling the need to make up legitimate-sounding excuses.
If you're caught off-guard by an invitation - on the phone or in person - Randall said you can offer something as straightforward as: "It sounds great, but I think I'll pass this time."
And if you're dealing with a person who's particularly sensitive or who doesn't like to take "no" for an answer, Randall said you can sweeten your refusal with something like: "It's so nice of you to think of me."
For people who don't seem like they're going to crumble to pieces if you decline, you can go with something that sounds a little harsh, but that definitely gets your point across: "I'm not interested; thanks. Keep me in mind for the next event."
The important thing to remember is to keep it short and simple. Here's Randall again:
"The less dramatic [we are] when we decline an invitation, the better. We tend to get wrapped up in it because we don't want to hurt their feelings: What are they going to say? And that's when we end up either saying 'yes,' or digging ourselves deeper and making more and more excuses."
