One thing, that should have no place in our life is destructive relationships. They are to be deleted ASAP- from your life, from your friend list, from your contact list, from your mind, totally deleted.
An then what just remains is positivity in your life. Stay away from people who give you negative vibes. Filter and keep only positive ones. People who do not respect you, do not love you, do not value and cherish you, should be immediately handpicked and deleted.
