Explain how you and your life change if you accepted that change was not an exception but the rule?

The Dao symbolizes a reality that is ever changing, ever fluid, but with a continual alternation between two elemental forces, the yin and the yang. Explain how you and your life change if you accepted that change was not an exception but the rule? I once told a student: “All we want is certainty but all there is is change.” She told me she wrote it on an index card taped to the mirror so she saw it every morning. What do you think?
