Thank you for giving me a few moments of your time.
Every moment—well, minus the 1/3 of my life when I’m horizontal and unconscious—I have the power to exercise my free will to decide what to do with my time. Since you are on the Internet, you likely also have this power and freedom. (Many people do not.)
Which moments do I regret? The ones where my choices were not intentional. Moments where I was habitual. Moments where I was reactive.
