Community is the group of people you surround yourself with on a daily basis. This is a combination of family, friends, soul tribe. It's the group of people that you place your trust in through the good and bad times. It doesn't really matter how long you have known them or how you met them, as long as you feel like it's a person you can trust and grow with then they are a part of your community. 

Community is important for a multitude of reasons. When life can become really really good, community is there to celebrate you and lift you up. When life becomes chaotic and depressive, community is there to hold you as you work through the situation. They are the ones to hold you accountable and love you. We have desires to be accepted and loved by someone. It is in our biological makeup. Community helps fill this desire.
