Human life is full of defeats and victories, complex realities, and uplifting joys. To navigate inevitable challenges successfully, one needs psychological resilience, determination, and optimism. I would like to focus on optimism as a source of hope and self-empowerment. As Winston Churchill said, "The pessimist sees difficulty in every opportunity. The optimist sees opportunity in every difficulty." Nevertheless, it's important to balance optimism with a realistic worldview, maintaining harmony between positive thinking and real-life challenges. I would like to discuss: How can we balance optimism with a realistic worldview?
