Hi Overwhel:
There are two types of Career Aptitude Tests - the free one and the one you pay for.
The free ones are set up for purely entertainment purposes and if you pay attention, they will include a disclaimer in small text to avoid getting sued for an incorrect outcome.
I would suggest you find a reputable Career Center for your area and take one of their tests. Why? These tests are set up for you as an individual and there is a professional to help you with the results and any career questions you may have.
You can also sit down somewhere where it is quiet and make a list of all the jobs you have held in the past and present. Under each job list what you liked or disliked about each. Next think back to your childhood dreams. Have those changed? Do you have new dreams? Once you have this material in front of you, now comes the fun part. Find income sources that have a lot less of your dislikes and some of your dreams. Yes, we all have to make an income to pay our bills but why settle when we can pursue our career passion. This passion is what keeps people going when times get rough or challenging.
If you are still in a school of any kind, you can check with a Guidance Counselor or Career Advisor to see if they have any tests you can take through their department. The good part about this is the fact that these people usually know what jobs are out there and the best way to figure out which one is a fit for you.
Talk to people who enjoy their jobs and who are also in careers you may have an interest in. They can share their career journey and may have some job leads to pass your way. Going back to school may be an option for a total career change if you are working now. But sometimes all it takes is transferring into another department and getting some on-the-job training. Be open to what is out there, figure out what you can offer and then do some research. Your insides, not anyone, will tell you what career path to follow. A lot depends on whether a high salary is more important versus job satisfaction.
