Picture yourself vividly as winning, and that alone will contribute immeasurably to success.

The line expresses a classic early–20th-century emphasis on the power of mental imagery and expectation: to “picture” success is to prime attention, confidence, and persistence toward the behaviors that make success more likely. It implies that inner rehearsal—holding a vivid, affirmative picture of the desired outcome—can shape outward performance by reducing hesitation and strengthening resolve. At the same time, the wording (“that alone”) leans toward motivational rhetoric rather than a literal causal claim; its significance lies in encouraging agency and disciplined optimism, not in denying the role of circumstance, skill, or opportunity.
