The ancient Greeks used to have a saying - “know thyself”. This was carved into stone at the entrance to the Temple of Delphi (you know, the one where that priestess chick got high all day long). No one can figure out which famous Grecian came up with that saying, but the meaning is clear: it's important to understand who you are.

I love personality tests and theories. I talk fanatically about my zodiac sign and I’m a sucker for those Myers-Briggs movie character charts that are always circulating on Pinterest. I know that many people find that hobby ridiculous, but I think reading about yourself is (1) fun, (2) interesting, and (3) revealing. Plus, my therapist says I’m very self-aware ;)

Read on for my four favorite personality tests/theories. Maybe you’ll learn something about yourself on the way!

• Myers-Briggs: Okay, so if you’re in college, chances are that you’ve taken a Myers-Briggs test. It’s probably the most widely known and used personality metric out there, but for good reason. The test consists of 93 questions that have 2 answer choices each. At the end of the test, you are given a four-letter acronym for your personality type. There are 16 different personalities recognized through this test - 2 options for each letter. Your results will also show you how heavily you lean towards one trait or another.

Pros: Well-researched, lots of literature available to read about the types.

Cons: Not a good test for people who tend to react differently depending on the situation.

Where to Take It: There’s no official version of the test available for free online, but check with your school’s counseling center or career development office. They often have access codes available for students.

• Strengths Finder: This is another personality test that’s pretty well known in the business world, and I’ll be the first to say that I vastly prefer it to Myers-Briggs. The test has 177 “questions” - you choose which of two statements describes you the best. At the end of the test, you are given a list of your top 5 strengths, listed in order of dominance. I found the test to be super accurate, and it’s neat to see something you would have described as a “quirk” listed as a strength.

Pros: With 34 individual strengths delineated, you’ll probably never know someone who has the exact same top 5 as you. Gives you good answers for the “what is your greatest strength” question in job interviews.

Cons: The test is super long and you only get 20 seconds to answer each question, which can be stressful.

Where to Take It: The book Strengths Finder 2.0 by Tom Rath comes with an access code for the test, but once again, check with your school to see if they have a free version for you.

• Enneagram: I had never heard of an enneagram until this past July, when my two best friends introduced me to this personality theory. The enneagram has its basis in ancient teachings about personality. Essentially, an enneagram is a circle with three triangles in it, and each point of the triangles is equivalent to one personality type - 9 total. You have one dominant basic personality type corresponding to your number, and the other points of that triangle are connected to your personality type and tell you more about yourself. While a confusing concept, I found it to be very accurate.

Pros: You should be able to strongly self-identify with one of the nine personality types. When I first read through the types, I immediately knew that I was a Three. I took the free sample test after I had read about being a Three, and it confirmed my ennea-type.

Cons: If you don’t initially resonate with one of the nine types, you probably won’t find this theory to be very useful.

Where to Take It: I would recommend just reading through all 9 personality types online. You can find the list here. If you want to go further, you can take a free online sample test or the $12 full length test through the Enneagram Institute.

• Zodiac: I know you’re probably shaking your head right now, and I’m right there with you. We all know that zodiac signs are (at best) pseudoscientific and (at worst) teen magazine fodder. However, I have found that my zodiac sign, Scorpio, describes me in most scenarios. If nothing else, knowing your zodiac sign is fun, and you might learn something about yourself from reading up on it.

Pros: No test required- your birthdate determines your zodiac sign.

Cons: There is no real basis for assigning specific traits to specific months, so yours could be wildly inaccurate.

There ya have it, the four personality theories guaranteed to make your therapist love you. Go find yourself, grasshopper.
