You will not hide your true feelings for long. Some try to do so by self-control. This is not the answer. It takes an effort that pits your mind against your own Self to do so. Life is all about being who you are, the real you. The Self will not be controlled, for long. Any effort to do so will last for a short time. At which point your control will lose its grip and your hold will give way. That is when we will act the way we really feel. This is what you are trying to hide when you use self-control. It happens when a thing you have worked for is at stake and it is close at hand. If it does or not, what is for sure, you will lose self-control at some time or place. You must strive to be self-aware, that you will not lose once you have it. To be self-aware, is to know who you are. It is your core. It is the Self.
