I get on my nerves quite frequently.
One of the things that I do that irritates me the most is when I talk for the sake of talking. I really cannot stand that. As I am speaking, I am mentally kicking myself. What I just said had no purpose and often comes out all tangled and unable to be understood. I want to speak with a purpose. Have something to say, think through it, and then say it in a short, precise manner. I want to talk with a purpose.
