When beginning a new relationship, most people fit into one of two categories: those who look before they leap, and those who leap before they look. There's nothing wrong with either — your personality simply dictates whether taking it slow and steady or falling hard and fast is more your style. When it comes to Myers-Briggs personality types that won't rush into relationships, you'll find that those that who it slow tend to value quality over quantity. While it may take a while for these MBTI personality types to find love, it's often because they're trying to find a partner for life.
People who take their sweet time starting a new relationship aren't necessarily being picky — more likely, they're just being deliberate. They don't want to commit unless they've found a partner who shares their interests and values, as well as a partner who is in it for a long time, not just a good time. Not sure what your personality type is? Take the test to find out. It may be the case that your personality is better suited for easing your way into relationships, so don't feel the need to rush into something — when you find the right person, you'll know it.
