accomplish something great

I had a mock interview with a professor two days ago. He told me I needed to demonstrate more accomplishments from what I had on my resume. I am still at a loss as to how I can do this, since many people have different opinions on what constitutes as an accomplishment. I see many of the things Ive done as personal accomplishments, but I have yet to really have any public accomplishments. I need to look at my natural stregnths and see what I can start working on that will help me develop a specific goal so I can finally accomplish something great.

There ya go, I did it.
