Could we change our attitude, we should not only see life differently, but life itself would come to be different.

The line proposes that perception is not merely a lens laid over an unchanged reality: our “attitude” actively shapes what life becomes for us. Mansfield frames inner stance—habitual expectations, emotional posture, readiness for joy or resentment—as a creative force that reorganizes experience. Changing attitude would alter what we notice, how we interpret events, and how we respond; those responses then feed back into circumstances (relationships soften or harden, opportunities appear or vanish). The quote thus sits at the intersection of psychological insight and moral exhortation: it suggests that transformation begins internally, and that the world we inhabit is partly the world our dispositions help to make.
