Preparing for my first interview in 4 months (Sacramento)

I get tongue-tied when I am asked about my weaknesses. I do not usually post, so bear with me. I have practised answers but they sound stiff. What calms you down?

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

Arrive early, drink water and take a slow breath before you walk in. It sounds simple but it helps.
