After reading descriptions of your 4-letter type, ask yourself how well they describe you. If you feel that the descriptions of your type do not fit you, read an explanation of what the letters represent. Decide which letter may not be a fit and substitute it.
Most people find a true fit can be found by changing only one letter, if that.
If some confusion still exists in your mind, you might ask the assistance of someone who knows you very well, set aside the results for a few days or longer and see if coming back to it later makes it clearer. They are only as valid as the responses you indicate.
