Your home is your sanctuary. Only place things in it for comfort & convenience. Have arrangements of furniture and items in it which bring you comfort & peace. Only allow people over the threshold that wish you well. Be particular about your visitor list.
Be vigilent; people will know you through and through when they see what you surround yourself with; do you want just anyone to be familiar with your passions? I believe it is wise to invite only positive, loving people into my home.
