When you try so hard to look normal in front of anyone that you fake everything even about what you're lacking of (like confidence) just because you don't wanna seem different/abnormal and don't want people asking you questions.
And then, you realize that you're a really good actor/actress and think it might be a good idea to start an acting carrier but then realized it involves being a center of attention, cameras, talking to lots of people, and way beyond the comfort zone that you just shake the thoughts off because it scares the sh*t out of you.
