I am a big believer in taking what you want to feel happy. For me this is something that is true in all areas of life. I promote positive parenting and I constantly send out the message to do what feels good for you. Do what feels right for your family.
The same message is true for people learning the law of attraction. Some things you hear will feel good and others will not. Again, take what you like and leave what you don't.
The number one way to block the things you want from manifesting is to do things that don't feel good to you.
