Who adopted and made this motto famous, "Be always sure you're right-then go a-head!" ("First be sure you're right, then go ahead.")?

Davy Crockett was born on August 17, 1786, in Greene County, Tennessee. In 1813, he participated in a massacre against the Creek Indians at Tallushatchee and later earned a seat in the 21st U.S. Congress. He was reelected to Congress twice before leaving politics to fight in the Texas Revolution. On March 6, 1836, Crockett was killed at the Battle of the Alamo in San Antonio, though the exact circumstances of his death have been the subject of debate. The myth of Crockett was commodified for children during the 1950s as part of the popular Disneyland TV series.

No matter how fascinating or outrageous the fabrications were that gathered around him, the historical Davy Crockett proved a formidable hero in his own right and succeeded Daniel Boone as the rough-hewn representative of frontier independence and virtue. In this regard, the motto he adopted and made famous epitomized his spirit: "Be always sure you're right-then go a-head!" Or " First be sure you are right, then go ahead!".
