Honesty is the cornerstone of all success, without which confidence and ability to perform shall cease to exist.

The saying frames honesty not as a private virtue but as the structural “cornerstone” on which durable achievement rests. It argues that success depends on trust: once honesty is absent, others’ confidence erodes and even genuine competence (“ability to perform”) becomes ineffective because it cannot be relied upon or believed. The quote also implies a practical business ethic—integrity sustains reputation, relationships, and organizational cohesion—suggesting that short-term gains from deception ultimately undermine long-term performance. In this view, honesty is both moral principle and strategic necessity, making success inseparable from credibility.
