If you are considering a new career and not sure what line of work is right for you there are a lot of online assessment tools that can help you on your path.  One of such tools is called the Myers Briggs Type Indicator or MBTI.

The MBTI is an assessment tool that assigns one of 16 personality types based on an individual's personality traits.  Once you have taken the assessment you will be told which personality type best fits you based on the answers you provided.  The results will tell you which situations you thrive in and where you get your energy from.  Gaining this knowledge will give you the ability to make much more clear and intelligent decisions about your life and career path. 

I have taken the Myers Briggs Personality Test and I highly suggest everyone takes it once in their life.  It definitely is not an answer to all your questions but it will definitely help give you a better picture of yourself and how you can be successful and happy in your career.
