A lot of people come to me and say, "Ethan, I have a problem distinguishing my personality type. I don't know if I'm an ISFP or ENFP, it feels like I'm a little of both. "
Many people struggle to gauge their personality type because of the many environmental factors that ultimately affect human behavior. Because of different cultures, upbringing, training and experiences, a person can show various behaviors according to the situation they're in.
If that's you, it's normal. In fact, it's healthy!
A normal healthy individual learns to use different aspects of behavior. For example, an healthy Introvert learns to communicate actively by speaking and interfacing in a networking session. Likewise, a balanced Extrovert is one that listens as well as speak.
So it's normal that individuals display all aspects. What is more important, when trying to find out your personality is:
Personality is ultimately not a gauge of how you behave, but how you PREFER to behave.
This means that sometimes you may not like to act in certain way, but you do so because it is appropriate for the situation. Using the same example, it is more natural for Introverts to keep to themselves, but it would be extremely inappropriate to keep to oneself in a networking session!
It is often your behaviors that have changed and evolved according to your unique training and experiences. However, your personality preferences remain the same.
Let's use the same example: being an experienced salesperson or entrepreneur, you've learnt to make small talk and conversation with many people, however being an Introvert, at the end of the day, you still prefer finding some solace and quiet in the comfort of your home.
That's the idea of personality preferences - it just tells me how you prefer to behave. It doesn't tell me how you choose to behave.
You can reference this section if you are unsure of your personality type and hope to find some clarification. Hopefully, it will help you get a clearer picture of which of the 16 you really belong to.
