Regret for the things we did can be tempered by time; it is regret for the things we did not do that is inconsolable.

The saying distinguishes two kinds of remorse. Regret over what we did—mistakes, harms, embarrassments—can soften because time brings distance, repair, forgiveness, or reinterpretation. By contrast, regret over what we failed to do is framed as “inconsolable” because it resists closure: the unrealized alternative cannot be tested, corrected, or redeemed, and imagination keeps it alive as an ever-possible better life. Harris’s antithesis functions as counsel as much as diagnosis: it urges action in the present, suggesting that the pain of omission (not speaking, not trying, not loving, not leaving) may outlast the pain of commission.
