Misconceptions

I fumble for words today, struggling to generate coherence, energy, humor. Grumpiness threatens, looming over me like humidity, beating me down.

Writing about how people misperceive me confuses me a bit because I could be wrong about people's perceptions. What if I think people perceive me as nice, and they don't? I don't want to be wrong. Instead, I think I'll write about a misperception of someone else in the project. Here's my description of her:

Sweet, but steely, fortified by an inner determination to succeed, eager for improvement, welcoming of criticism--the misperception is that she may fold under pressure.

Do you know of whom I'm writing?
