Write about a situation where you had to choose one option out of many? What did you choose? What was its impact on your life?
There are so many ideas you could use to write this essay. Even as a young person, you have already made choices among different options, and these choices have had an impact upon your life. You could have chosen to learn one foreign language and not others. You may have made a choice what college to attend. You may have made a career choice for yourself. You may have chosen a girlfriend. You may have chosen to befriend or not befriend someone. If you are out on your own, you may have chosen where to live or what job to take. You can discuss this within the context of the poem, if you like, to compare yourself or contrast yourself with the narrator. You may have chosen the less-traveled path or a more well-traveled path.
Once you settle on which choice you want to write about, you need to think about what the consequences were for this choice. For example, if you chose to learn another language, that may have opened up doors for you in education or work that otherwise would not have been open to you. Which college you have chosen has consequences in what you study, who your friends are, and where you live. Your career choice obviously has many consequences. The choice of a girlfriend or a friend does, as well. Either can change a person's life. Where you work and where you live create many consequences for you. Once you have settled on which consequences you want to discuss, you can use those to write a thesis statement for your essay, stating what the choice is that you are going to discuss and what the consequences are that you will write about. That thesis statement should be the last sentence in your introduction. Then you can write body paragraphs, one for each consequence, and wrap it all up with a conclusion.
