1. They challenge you to stretch yourself.
Maybe you're super reserved and don't go out much in groups. Your more spontaneous, extroverted friend will be able to push you and encourage you to attend more social events or to try new activities with your peers.
2. They give you a unique perspective.
Friends that see the world differently than you are the ones who can offer insight you would otherwise never consider. If you're prone to overthink situations, try asking advice from someone who is known for having a more objective personality.
3. You gain better communicative skills.
When you have friends that have different personalities than you, you must learn to communicate in new ways. You figure out which ones prefer to talk about life, which ones need to be listened to more, which ones hate small talk, etc.
4. You learn how to deal with conflict.
When you're surrounded by different types of people, there is bound to be conflict. This is normal and expected. The great part is, you just cope with this conflict by learning to be more confrontational or more sensitive to others' feelings, depending on which one doesn't always come naturally to you.
5. It's real life.
You're not always going to be able to choose who you're around. Your coworkers, classmates, and family members are bound to vary in personality, but that should not limit your relationship with them. This is real life, full of real, unique people.
6. You become more exposed to different social dynamics.
When you have a variety of personalities in your group of friends, you will realize that some prefer one-on-one time, while others are more expressive and comfortable in bigger crowds. In order to grow in your friendship, you may need to adapt to a variety of social dynamics and learn what each one is like.
7. You learn how to love others despite their differences from you.
Is it really love if we reserve it for those who think and act just like us? Learn to love despite differences. Even if the person is your complete opposite.
8. You stay humble.
Instead of sticking to friends that only strengthen and back up your own opinions, you will be given opposing viewpoints and constructive criticism. You will be less likely to be judgmental of others' opinions or prideful of your own.
9. You can empathize with and understand others better.
By listening to the different ways each of your friends perceive the world around them and what is on their minds, you will find it easier to put yourself in their shoes and show empathy for them in their unique struggles.
10. They add spice to your life.
Variety keeps life exciting! Why not change it up and surround yourself with people of all personalities who will help you grow and change for the better? There may be challenges as you realize not everyone thinks like you (crazy idea, huh?), but it's a risk that is definitely worth taking.
