set one's sights on, to

To select as one’s goal. The sights in this expression are a device such as a pair of knobs or notches placed on a firearm to help one take aim. The figurative use dates from the mid-twentieth century and also appears in such phrases as to raise one’s sights, meaning to aim higher, or to lower one’s sights, meaning to be somewhat less ambitious. The Economist used it on December 9, 1950, “The United States must now raise its sights, in terms of both manpower and production.”
