Talking to agents can be intimidating. I still sometimes get intimidated talking to agents, and I work for one. But, they are still human.
In my experience, whenever I start to feel too cocky, I do something really stupid and unprofessional. Today I accidentally sent somebody an email saying their manuscript was not a good fir for us. Yep. Not a good fir.
And I’ve seen similar mistakes from industry professionals who rank higher than lowly intern. We’re all human here.
Just keep that in mind.
