This is an important question. Essays can be hard to write. If you are writing an essay on personal responsibility, then you probably first want to define what you will mean by personal responsibility. After this important step, you will need a thesis statement.
A thesis statement is the main point of your essay. For example, your thesis might be something like: "Personal responsibility is an important step in growing in maturity.
After this point, you will need body paragraphs that support your thesis statement. In other words, what reasons do you have to believe that personality responsibility leads to maturity.
Finally, your essay should have a conclusion, which wraps your ideas up in a memorable way.
