Be productive in your works. As a student I should do my work with diligence because "if the ax is dull and its edge unsharpened, more strength is needed but skill will bring success." (Ecclesiastes 10:10) Another plus for being proactive and keeping this habit up is that it builds a strong foundation after our school lives. So be sharp in what you do, be effective teenager. God sees our every deed and it is our duty to live our life to its fullest, which that fullness comes from obedience and life in Christ. Most important is being proactive in seeking our God's face, because our lives are in His will. .

"Whoever obeys his command will come to no harm and the wise in heart will know the proper time and procedure. For there is a proper time and procedure for every matter, though a man's misery weighs heavily upon him."(Ecclesiastes 8:5-6) Put first things first is another habit in becoming an effective teenager. It is hard for us today to know what comes first and what comes last. We are too easily preoccupied and majority of our time we are preoccupied with the wrong things, which is waste of our time and being defective in our life. God tells us to put Him first. Obeying and listening to God shows Him that you fear Him, and "the fear of the Lord is the beginning of wisdom."(Psalm 111:10) It sounds very simple and hard to believe, but it is true, putting God first will help put all things in its proper time and procedure. He says in His word that He"ll provide you wisdom if you ask; so have faith in Him. This is a huge challenge to lots of the teenagers that have been defected, because the majorities have a distorted view of priorities in life. Distorted priorities like the clothes we wear, how we look, money, creating many idols. With that distortion come confusion, stress, anxiety, and all of which God wants to relieve all teenagers from. Therefore obey His commandments and He will relief you of your stress from school work, or family issues, etc, and provide you with wisdom to help sort out your schedule.
