Everyone makes mistakes. But learn from them and act accordingly in the present and future. Work to make mature and responsible decisions in school and outside of school. Learn how to manage your personal finances competently. Avoid any brushes with the law or academic disciplinary entities. Be aware that criminal or disciplinary violations of any magnitude have to be disclosed and explained on law school applications. More serious violations, such as having a felony conviction or and several misdemeanors, are likely to be discovered and may prevent you from being accepted into law school and/or sitting for the bar exam. In short, act and behave like a mature and responsible adult in order to avoid any of these sorts of difficulties that will probably short-circuit your law school ambitions and/or torpedo your post-law school career plans.
