Success is achieved by developing our strengths, not by eliminating our weaknesses.

The remark contrasts two approaches to self-improvement: shoring up deficiencies versus cultivating what one already does well. It argues that “success” is more reliably produced by investing time and effort where returns are highest—turning talents into distinctive competencies—rather than expending disproportionate energy trying to become average at everything. The quote also implies a pragmatic view of human limits: weaknesses can often be managed, delegated, or worked around, but strengths can be compounded into expertise and advantage. In modern terms, it aligns with strength-based development in education, management, and personal growth, emphasizing leverage over remediation.
