What is your greatest weakness?

"My greatest weakness is public speaking. I can speak well in a meeting or conference where I know the people I am speaking to, but I get nervous when speaking in front of people I do not know. At my last job, I recognized this as a weakness when my supervisor asked me to put together a presentation about abstracting medical information to present to a medical facility. Even though I knew my job inside and out, I froze at the podium. I was able to present the materials with the help of my supervisor, but I knew that I had to address the situation for future presentations. I enrolled in an adult education public speaking class at the community college and have been perfecting my public speaking skills. I have three months left in the class and already feel that my skills are improving."
