To know the importance of family is to accept unconditionally every member's flaws and assist them when necessary. Being a part of a family helps you form character which you will take into adulthood. Recognize that what your family has taught you is the stairway of stepping stones every person blindly uses until he reaches the age where he can make his own decisions.
Remember, your family were the first people who loved and cared for you before your character was truly formed. Family allows you to be yourself no matter what the circumstances are. The building block that family has developed in each individual is unique in some way, but primarily the same.
The basic values instilled in you by your family never leave, no matter where you may end up in life. When a storm falls into your life is when you need the people that you call family the most because they will not turn their back on you. The importance of valuing your family is something that is handed down to every generation and the elders in the family try to remind the younger ones of the values they are to uphold after they leave the family house. The younger ones are reminded of upholding their family's value because they are a representative of the whole family when out in the world.
One thing everyone should remember is that family is for life. Even when you decide to disassociate yourself from them they will be there waiting for your return with open arms. As an adult it is best to remember that family helps not only in shaping you as a child but they also help you to improve your daily overall life. Family can assist in this because they know your true personality, accept your flaws and yet they are still willing to provide a protective layer over you while you work on improving your personality. This is yet another example of the importance of family.
