There are no secrets to success. It is the result of preparation, hard work, and learning from failure.
Make this a year in which you focus on your work ethic. Prepare well for classes, papers, tests, whatever. Ask for help when you need it, not because you can’t understand something but because you want to improve your knowledge and skill. Look at what didn’t go well last year and think of ways to avoid repeating those events or circumstances. Work hard, not for a grade, but because you want to see just how much you can achieve.
