How do you know it's any good?

This week I've been in deep revision mode and I was on deadline for an article that will be published in the June/July issue of Tu Ciudad! Busy! Busy!

But the other day I was nosing around online and came across a message posted from a writer who asked when do we know a story is any good? How do you know if its worth pursuing?

For me, it's gut instinct. If the characters come to life and refuse to go away until I finish their story, then I know this is a journey I have to complete. I don't judge if the story is "good" or "bad." My agent does that for me. How I feel is that every story and character who has come into my life has done so for a reason.

Right after I turned in In Between Men (waaay back in September 2004), I wrote a drama about two sisters who never knew the other existed until their father was diagnosed with cancer. I loved the characters Dori and Sela, but the story was so so. I talked to my agent about it she asked me what I was doing writing a heavy-handed drama when I've been writing comedies? Unfortunately, she has a really annoying tendency to be right and that story has since become an organ donor.

But I missed those sisters. Five or six months later, I was at a wedding and while eavesdropping on a conversation, found the story for Sela and Dori. Next month, "Till Death Do Us Part" will be inflicted on the reading public in Names I Call My Sister.

I'm not sure if I successfully answered this question. For those of you writing out there, how do you know if your story is "good enough"?
