The person who makes a success of living is the one who sees his goal steadily and aims for it unswervingly.

DeMille’s line frames “success” less as luck or talent than as sustained intentionality. To “see his goal steadily” suggests clarity of purpose and the discipline to keep that purpose in view amid distractions, setbacks, or shifting fashions. “Aim for it unswervingly” adds the ethical-psychological dimension of perseverance: progress comes from repeated alignment of daily choices with a chosen end. The quote also implies a hierarchy of values—life is “made” successful by deliberate direction rather than passive drift—echoing a common early-20th-century self-help ideal that personal character and focus can shape one’s destiny.
