Positive and negative emotions cannot occupy the mind at the same time.
People often feel stressed before making a big presentation.
Of course, that’s normal if the stakes are high.
However, to cope with those feelings, you have to be able to give new meaning to what you are feeling.
For example, feel “excitement” rather than “stress”.
Focus on the pleasure of sharing and what you are offering your audience to build a positive mindset and drive any negative feelings away.
