Jane, I agree with you re's the power of positive thinking... but there are people in the world who both believe in and practice the laws of attractions... like attracts like and money attracts money, etc . . .
Take Suze Orman and what she teaches as one example. She has stated in books and TV that if one dreams enough and believes in their dreams, stay positive and do the mantras, etc ... they will get from the universe what they asked for. It's based on a spiritual philosophy. She teaches millions of people through her books how to be positive and how to embrace where they are in life - if they're poor they need to learn to accept and embrace being poor . . . What you put out into the universe will come back to you from the universe, has been her motto for years. Years ago I heard her on the Oprah show telling people that if they do the work, dream of receiving a check, blah blah, it will come. She stated that people should write checks to themselves and put them in their wallets if they want to receive money...
All that said, I haven't bought any of her books and I don't follow her so I can't say if it works or not; just that people believer in it and work it.
