Nowadays it is not enough if you are good at something, you must be able to present it flawlessly as well. I was asked several times for job interviews to prepare a presentation as a prework for the interview. However according to some studies a huge percentage of people are actually fear more of public speaking than death. I believe that if you prepare properly and practise, you can be a master of presentations. Some of us feel more natural to be on the stage, others of us spend a lot of time practising to get used to it. But it is a skill which can be developed. You can develop too.
