<human>:  How can I calm my nerves before a big presentation?
<bot>: Taking deep breaths and counting to ten can help to calm your nerves before a big presentation. Practicing your presentation beforehand and visualizing yourself giving the presentation successfully can also help to relax. Setting a routine before you give your presentation like listening to calming music can help to ensure that you are relaxed and focused. Stretching or taking a quick walk can also help to reduce your anxiety.
