“Focus.” The Hebrew word is nabat (#05027 נָבַט), which means “to look,” and here the verb is in the Hiphil aspect, meaning to regard with one’s mind and sight. So it seemed like “focus” brought out the meaning of the verse more than just “look.”
God is not telling us in this verse to physically just look straight ahead and never look around; that would be foolish. In the idiom of Scripture, looking straight ahead is looking at the things of God, and also looking at the future. In Scripture, people who look to the side or turn to the side are turning to the ways of evil.
