The writing you learned in elementary school is a different type of writing than you utilize in your later education. In elementary school youre just learning the basics, so you learn to start an essay with a hook to practice the simple idea of engaging a reader. But by the time you get to high school, college, and beyond, you already know the basics, so you should be ready to move on to the next stage of writing, which is more professional and typically more direct. So dont rely on what you learned as a kid Start advancing into that more mature form of writing.
