Make two important lists for expressing your Gratitude toward the Universe.
The first list contains the listing of Your 10 Most Important Blessings, which is, your most obvious gifts and talents as you received it by birth and/or developed later on in your life. It does not matter if you are using those talents professionally or not, express the gratitude that you have received them, that they are at your every day disposition and contribute to the Joy of your Life.
The second list contains Your 10 Most Urgent Desires, which is, what you wish to positively attract into your life, be it money, relationships, jobs, opportunities, material things, or immaterial things like fame or reputation, it does not matter, just list it all. End every statement with ‘Thank you, thank you, thank you’ and feel in your heart that what you desire, you have received it already, instantly, the moment you expressed your wish to the Universe!
Do not think long to draft these lists in order to avoid intellectualizing your statements. They should come from your gut and be expressed in fast, consciousness-style writing so that your subconscious mind contributes in drafting these important statements.
Then, read both lists aloud to yourself every day twice, once after waking up and once before you fall asleep.
See in the Comments section the two statements I have myself posted that, while they contain my personal blessings and desires, can serve you as models as to how to best draft these statements.
If you are not sure how the Law of Attraction works, read The Secret or watch the film, or both. I have reviewed the book here.
