Extraversion (E) vs. Introversion (I): How you get your energy (from being around people or from quiet time alone). Sensing (S) vs. Intuition (N): How you take in information (through concrete facts or through abstract patterns and ideas). Thinking (T) vs. Feeling (F): How you make decisions (using logical logic or personal values and how it affects people). Judging (J) vs. Perceiving (P): How you deal with the outer world (by having a planned structure or being flexible and spontaneous).
After doing the above questions you will have four letters (I'm a ENTP). I would search up "Personality for ENTP." The answers will usually be very accurate!
