One of the best things I get from going to conferences (besides the information and critique sessions with real live agents, editors and writers) is my growing number of contacts.
The KS conference was quite a coup in terms of the great friends I made. In the weeks since the conference, I have joined an online critique group for picture book writers; I have established a relationship with another budding critique group for short story writers, and I talk regularly with new writer friends around the midwest.
I was debating whether to attend the MO conference because of its close proximity to the KS and national conference in NY (which I am going to for the first time...yikes!), but I decided to give it a go again this year primarily because of my wonderful experience at the KS conference. I'm sure I'll see some of my friends there, and I hope to make new ones.
If you are an aspiring writer and have ever wondered whether it's worth your time to go to a conference, then wonder no longer. Go! Go! Go!
