"[W]hen He, the Spirit of truth, has come, He will guide you into all truth." - John 16:13
One of the books I like to use in helping students to find their own initiative and grit is James Clear's, Atomic Habits. It is one of the most pithy and quotable books of its kind, and it offers very practical helps for people trying to create change in themselves.
In the introduction, Clear states, "As long as human behavior is involved, this book will be your guide" (p.10). A confident claim, to be sure. And it begs the question, If I am a Christian, should I trust this kind of advice? Don't I already have a guide? Indeed, you do.
For all Believers, the Holy Spirit lives in us, and - as Jesus says to His disciples - He will guide you into all truth. Am I to take it that I should then refuse to hear others who claim to be guides? I don't think so. Instead, I practice and recommend that all we absorb and engage should be placed under the supernatural guidance of the Holy Spirit: Almighty God and Father, I ask that Your Spirit would help me to see and embrace truth, and to discern and reject lies. I trust You to do this in me by Your Spirit, because of Jesus, Your Son and our King. And Amen.
The book, Atomic Habits, may be a big help to me and my students. And I pursue all good things under the blessing of God, including the perfect guidance of His Spirit.
