on second thought

After reconsidering. This phrase, which often precedes announcing a change of opinion or decision, has been around for centuries. Many writers have proclaimed that second thoughts are superior to first; Euripides, Cicero, Sir Francis Bacon, and John Dryden all held that “Second thoughts are best.” Almost as many others have disagreed and maintained that second thoughts are markedly inferior, among them Lord Byron, Robert Fitzgerald, and the Earl of Shaftesbury (1711): “Men’s first thoughts are generally better than their second.”
