A mask disguises you. In a way it is to hide your real identity. When you wear a mask, you have 2 identities - the real identity, and the artificial identity. When you wear 2 identities, often people have difficulty knowing the real you. Many may mistake the artificial one for the real one. This mistaken identity will cause an identity crisis for you. People will not know who you are, and what you stand for. Tear off the mask.
We wear a mask because we are afraid to stand in our intellectual and emotional nakedness in front of others. We are feeling shy of ourselves, so we put on a mask. There is only 1 problem in this. The mask you put on will carry the burden of putting on an act. You will feel tense of pretending to be someone you are not. Stress has entered your life. It's not needed. Just be yourself. Tear off the mask.
