In such a volatile world, how can you possibly prepare for your future?
First, study the Bible. Regardless of where and if you go to school or what you choose as a major, the promises of blessing from knowing and following God's Word are incomparable. Many Bible scholars believe this verse in Daniel actually refers to Bible study: the eyes of scholars will move furtively over the text of God's Word, and our understanding of its precepts will increase like crazy as the time of Jesus' returns near.
Second, pray about taking a chill pill when it comes to overloading on the academics. Maybe you believe that if you don't get into the perfect high school, take every AP class offered, and spend every walking moment working, no decent college will want you. There is such a thing as spinning your wheels, working for accolades that fade as fast as spring flowers, and finding yourself bitter about the rat race. God is good, and life is good. Be sure you have enough time to say so with conviction!
Reset your weekly Sabbath if you've happened to let it slip.
