One of the most important tools you can use in writing successful is your own experience, and one of the most important steps you can take to be successful is to write for yourself, not for English composition class. Sure, I know that each and every one of you wants to write an essay that is going to impress me (and translate into a good grade). But try to put that aside. First and foremost, write for yourself. Pick topics you have an interest in, topics you want to write about. You will enjoy it much more if you have an interest in it. So write for your own pleasure first. The rest will follow.
