The Thoughts of a Writer

I’m struggling finding a topic to write about today. My mind wanders as I research literary agents to whom I can send a query letter. My heart races as I read their bios, each one offering different capabilities. What am I even looking for? I HAVE to find the right agent, but how? There are millions to choose from; how do I know which ones to pick? It is a daunting task, one that I am not taking lightly.
