If you are a high school student without clear direction about your future, you are not alone. Most high school students (and older people too) can benefit from additional self knowledge about their personality type, interests, strengths & weaknesses and likes & dislikes.

In terms of college planning, this awareness can help you define goals and select a college environment that suits you. Self-knowledge can also help you present yourself more articulately and confidently in your applications, essays and interviews, which can boost your chances for admission. The same information can be helpful to you in deciding on a college major and exploring potential careers.

There are some excellent self-assessment tools (many of them free and fun to do – you just need to know about them!) to help you. Many also provide a list of suggested college majors and careers that are compatible with both your strengths, general interests and personality type.
