Encouraging signs are symbols or messages that provide hope and optimism. They can be seen in many forms, such as posters, banners, and even tattoos. The term 'encouraging signs' is often used to refer to the acronym PATS, which stands for Positive Attitude, Teamwork, and Self-Confidence. These three elements are essential for success in any endeavor, and having encouraging signs around can help remind people of these important values.
