One thing that helps me when using statements (or affirmations) is to find actual examples in my life that make the statement feel true. Take statement number one - other people are not more fortunate or better off than me - and list some ways that you are well-off ... maybe good health, job, loving family ... whatever. Writing them down helps to solidify them in my mind.

Just 'saying' a statement doesn't bring it into reality for me - I have to see and know the actual ways in my life that the statement is true. And when a trigger comes up that is counter to the statement, I already have examples to disprove the mistaken idea in my head!
