Historians are found in many diverse career areas. The most important task for you is to determine which area fits most closely with your personality traits and meet and talk to people who are doing what you think that you might want to do, so that you can see what they do, how they got there, and what advice and suggestions that they might have for you.
Getting to know yourself and how your personality traits relate to people involved in various career opportunities is very important in your decision making process. During my many years in Human Resources and College Recruiting, I ran across too many students who had skipped this very important step and ended up in a job situation which for which they were not well suited. Selecting a career area is like buying a pair of shoes. First you have to be properly fitted for the correct size, and then you need to try on and walk in the various shoe options to determine which is fits the best and is most comfortable for you to wear. Following are some important steps which I developed during my career which have been helpful to many .
Ken recommends the following next steps:
Find the branch of the tree that is right for you. Academics in social sciences very often have a focus in certain part of the world. If your goal is to become a professor begin developing a passion for a certain area of the world and/or time period. This would be a great thing for you to know early on as you'll very likely need to get proficiency in the language of that region for graduate studies. If your branch of history is to be something like a museum curator that is a different matter. Good luck!
You have been given some excellent advice to get you on the right track for your goals. I am excited to see that you are so passionate about history. It it such an important part of our lives. We learn from it, we live it, we make it. To augment the guidance that Ken has given you, I recommend that you take a look at StrengthsFinder. It is my favorite assessment because it identifies your true strengths and provides recommendations on educational and career options. Best of luck with your journey.
