When first working with affirmations it is also important to use ones that feel belivable to you.
On the surface it looks okay and yet what the person is actually focusing on is their perceived bad luck with money! Read your goal card, every day, as much, and as often as you can until it becomes a habit.
Experimenting is wonderful way of finding what does work for you. Today I choose to create the best day of my life. If it does have merit, it seems that the message would need to be pretty personal.
Good luck and please let me know about your experiences as well! This will again reinforce it in you brain, thereby reminding you of your objectives. It knows all about you, loves you unconditionally and is always seeking to bring you up into higher and higher levels of vibrational flow.
Regular repetition will gently return your focus to manifesting the life of your dreams.
