There's a fine but definitive line between being a braggadocio and healthy self-promotion.

Wolfe Tone, who a few months before had patronizingly described him to Talleyrand as "a respectable old man whose patriotism has been known for thirty years," was now disgusted by the lying braggadocio with which Tandy persuaded the French authorities that he was a personage of great wealth and influence in Ireland, at whose appearance 30,000 men would rise in arms. Tandy was not, however, lacking in courage.
