Many people don't know how to choose the right time to speak up, or rather when an intervention is required from them, they don't dare to confront, but are satisfied with silence, and they cannot express any opinion or idea in the direction of a particular situation.
They may be afraid of offending a certain person unintentionally, or of speaking words that only people of sound mind can understand. Yes, silence is wisdom, but in some situations. Speaking out loud is what indicates your presence and makes others prepare a thousand accounts for you. Silence expresses your satisfaction with the current situation, even if you know that it is bad because you think that it will not involve you in any problems. It destroys trust and creates resentment. People rarely appreciate you for constantly withholding information.
Speaking up loud makes you more confident and preserves your mental abilities. Feeling your true self is important for character stability.
