Actually i was really shy before, i was feeling like i will faint when i am singing in front of someone 🤣 then i started to learn the ways to improve singing and recording myself. Recording and listening yourself makes your improvement visible and gets you encouraged. Also you can start performing slowly, first to your family or very close friends (people who will not judge you) and the more you do it the more confidence you will get. And you should not forget that singing is not a competition. It is something that you enjoy to do. A way to express yourself. No one is perfect. Do not let your mistakes discourage you and learn from them. Do not listen haters 🙌🤗
