Practice is always key for me. I will run through the presentation multiple times to check for possible words or phrases where I may stutter. Then I have the chance to find an alternative way to say it. I always have notes and sometimes just seeing the word written down helps me too. Take it slow, one slide at a time and add in a bit of humour if you’re comfortable; it’ll relax you. Either way however you do it, get it done. Good or bad, if it’s your first presentation it’s a valuable skill to have and practice. Good luck friend!
