Often feeling shyness covers a lack of knowledge about a subject。But you can easily change that。To be well prepared will strengthen your self-confidence。And，as I have written about several times，language is the tool。It might be difficult to train your conversation skills with a teacher or a professor，but in discussions with parents and friends you find a playground for presenting an opinion to a superior。And a little remaining shyness can be of help when it comes to politeness and emphasis。It makes you sympathetic，as we all have to deal with insecurity in one way or the other。
If you have to make a presentation in school or later to your boss and your colleagues and suffer from being nervous there is nothing wrong with saying：“I am quite nervous to speak in front of you all，but I will do my best。”I can tell you most speakers and actors are very nervous in front of an audience。
Today you might feel as I did when I was the insecure girl，embarrassed with blushing and angry because I couldn't help it。You can fight it。It takes time，but results will come。Today my mother and I laugh when we think of the times when she got angry at me because once more I quickly slipped into her little storage room to escape meeting someone。In those days neither she nor I would have believed that later in life I would come back to my hometown with my husband and give a talk in the local theater with more than 700 people watching。I am not shy any more。
