That's funny -- I started with telemarketers too!
My line was: That's not something I'm interested in pursuing, but thanks for calling and good luck with your sales tonight. (click)
I don't feel guilty at all any more.....I tell them what's true, acknowledge that they're not exactly doing their dream job, and get off the phone quickly and honorably.
There's a nice baby step.
And HK....you are a Yes Person to everyone....except yourself.
You count.
You're an important thing.
Your boundaries will set you free to live a wild and gorgeous life....AND PEOPLE WILL STILL LOVE YOU. Set boundaries with love (for yourself and for others) and you will have all you have now, AND all that's still out there waiting for you. It's not an either-or choice.
Love,
