To have regret is to be disappointed with yourself and your choices. Those who are wise, see their life like stepping stones across a great river. Everyone misses a stone from time to time. No one can cross the river without getting wet. Success is measured by your arrival on the other side, not on how muddy your shoes are. Regrets are only felt by those who do not understand life’s purpose. They become so disillusioned that they stand still in the river and do not take the next leap.
Progress, far from consisting in change, depends on retentiveness. When change is absolute there remains no being to improve and no direction is set for possible improvement: and when experience is not retained, as among savages, infancy is perpetual. Those who cannot remember the past are condemned to repeat it. In the first stage of life the mind is frivolous and easily distracted, it misses progress by failing in consecutiveness and persistence. This is the condition of children and barbarians, in which instinct has learned nothing from experience.
