Fear is an instinct that evolved to help humans survive threats but is often misunderstood today. While fear once compelled humans to fight or flee danger, it now provides a burst of energy that can be channeled productively, such as to overcome obstacles through public speaking with confidence instead of avoiding it. Similarly, humans must manage instincts like hunger today rather than avoiding things that cause anxiety. Fear should be accepted and harnessed as a tool rather than avoided at all costs.
