Take several tests, rather than just one. You will get a much better picture of your preferences and profile, not to mention career ideas, from three or more tests, rather than just one. Don't let tests make you forget that you are absolutely unique. An online test isn't likely to be as useful as one administered by a qualified professional in your community. Don't force online tests on your friends.
People are very skittish about tests.
Others don't like questions about how they would behave in certain situations, because they tend to pick how they wish they behaved, rather than how in fact they actually do. And some people hate all tests. End of story. So, trying to force these tests on your family or best friends could lead to your premature demise. Copyright 1999 by Richard N. Bolles.
