When you cage a tiger and deprive him of the wild, what do you think will happen? He'll scratch and pounce at anything, struggling to flee and get out. You'll only drive him wild, and he'll be upset for sure. You may sedate the tiger, but he'll never ever forget the nature of his being, the madness of his freedom. That's how anger will soon pounce and scratch at your
ego and confidence. No matter how hard you try to bottle it up, it will soon overflow and it may be too late before you can contain it. You're only creating your inner demon if you try to stop it. What will you do to a plummeting confidence level? How will you assert a true character if you'll forever keep mum? You'll end up frustrated and soon, without you knowing it, you'll punish yourself from anger. There's one life, once chance to make things right. Speak up and let yourself be heard, but do it in a right way without risking your health, hurting other people's feelings, and crushing your confidence. Be sharp yet calm and reasonable. All you need is to let it out with care.
