Threes and Sevens can look very similar from the outside in their default state, which makes it easy to mistake one (or yourself) for the other. They are both assertive, they like to pursue wealth and status symbols, they are likeable and outgoing. Both can show impressive accomplishments, and on lower levels of maturity, both can become quite narcissistic about them.
That’s why, for these types, it’s essential to look at why they do the things they do. Their motivations are where the big differences start to show. Sevens want to experience stimulation and excitement. When they acquire wealth, it’s for the pleasures it can give them. Threes on the other hand need validation and the feeling of being able to rise in status and recognition. When they acquire wealth, it serves as a status symbol and a sign that they belong to the cool kids.
That’s why Threes usually come across as much more composed and controlled – because that’s the image they want to project. Sevens don’t really care too much about what others think of them as long as they’re having fun, which makes them much more comfortable with showing their rough edges and emotions.
Threes make you want to be around them because they seem so successful and suave that you secretly wish to be like them. Sevens make you want to be around them because it’s just so much freaking fun.
