In what way will a youth merit to guard his way, as Solomon said (Proverbs 3:6), "In all your ways acknowledge Him, and He will make your paths straight." If you know God in all matters, He will direct your ways. Similarly, David said (Psalms 16:8), "I have set the Lord always before me; because He is at my right hand, I shall not be moved." And concerning this, David also said (Psalms 30:7), "O Lord, by Your favor You have made my mountain stand strong."
What enables my flesh to dwell in security? David said, "I know that deceit does not rule over my flesh." Thus, the righteous are content with no deceit, as they wait and search for what they may do to have a share in the World to Come. Therefore, David said (Psalms 16:11), "You make known to me the path of life."
Similarly, Moses said to God (Exodus 33:13), "Now therefore, I pray You, if I have found grace in Your sight, show me now Your ways." And he also said (Psalms 25:5), "Guide me in Your truth, and teach me." And as it is written (Jeremiah 6:16), "Thus says the Lord: 'Stand in the ways and see, and ask for the old paths, where the good way is, and walk in it.'" See which way Abraham walked and which way Nimrod walked, and which of them succeeded. See which way Jacob walked and which way Esau walked, and which of them succeeded.
