You can overcome anything if you don't bellyache.

Baruch’s line frames resilience as partly a matter of attitude: difficulties are not denied, but the habit of constant complaining (“bellyaching”) is portrayed as a self-imposed drag on action and recovery. The quote implies that endurance and problem-solving require conserving emotional and social energy for constructive steps rather than venting. It also reflects a pragmatic, stoic strain in American self-help rhetoric—valuing self-control, forward motion, and personal responsibility. At the same time, its bluntness can be read as dismissive of legitimate grievance; its force lies in urging agency, but it risks oversimplifying situations where complaint is a necessary step toward recognition or change.
