If you have a problem with a member of your family who is negative, begin by writing a list of all the things you appreciate about that person. Remember to include gratitude, because that person is giving you a great desire for positivity in your life. As you focus with all of your strength on appreciation, you will not only reduce your exposure to the negativity, but at the same time you will be attracting positive people into your life.
Get yourself on to the appreciation frequency, and the law of attraction can only surround you with people who are in a positive, appreciative state.
