Preparing for my first interview in 6 months after 12 years as a copywriter

I get tongue-tied when I am asked about my weaknesses. I am in Omaha, in case local advice matters. I have practised answers but they sound stiff.

Prepare three stories with a clear beginning, action and result, and adapt them to the questions.

I record myself on my phone and listen back. The second try is always better than the first.
