why do i feel nervous in front of the public and how i overcome nervousness?

assalammualaikum and a very good morning to all of you especially to our lecture SIR KHAIRUL NIZAM SHUIB. im YASMIN AZRA KHAIRULL ANUWAR student diploma in business management part 5 want to share my second topic for my assignment is "why do i feel nervous in front of the public and how i overcome nervousness?". this is difficult right? okay i don't mind it. everyone have a feeling of nervousness right? it is NORMAL. But sometimes it make we feel uncomfortable to show our confident and can build some negative thinking to do it. I never really thought much about a lot of things, and life was just easy and went on worry-free. I always was shy, and wished to be more outgoing, but it didn't ever really bother me that much. 
     I can see why people are afraid of speaking in front of a group. i standing up there alone. All of those eyes are fixed on me. Their ears are tuned to every word i saying. i really feel vulnerable. Naked. No place to hide. all this things already happen to me before this so it make to be a crazy person but even i feel like that it can make me to practice how to build a confident level to stand up there alone! i like its! 
     how i overcome my nervousness? okay the first thing that i do is i will make sure that all audience didn't see my nervousness when i standing up there that is because it want make them confident with my speech when my turn is around. i also must prepared! Obviously. If i have a presentation then study my notes and i was understand what i want to share about. second is, Practise, practise, practise. The more i practise it, take action and put myself in situations that may make i nervous the more confident that i get. i have been there before, i know pretty much what will happen. So i feel more and more comfortable and less nervous. 
     the third is i Realize that people don’t care that much about what i do. One big source of nervousness is focusing too much on what people will think of me. And thinking that their criticism is always about me. But people don’t think that much about what i do. i keep much of my attention from day to day on my problems, challenges and triumphs. And that’s exactly what the next guy/girl is doing too. for conclusion do not make our nervousness effect our performance in future. that all thank you.
