make it two seperate auto suggestions. You can use individually or together.
Teh second one "I am positive" might need a bit of work. Ever hear someone retort when told they need to be more postive?
It goes something like "I suck at this." Next person, "you need to be have a better attitude than that if you want to get better at it. Think positive." First person. "I am! I'm Positive that I suck." 
The mind reacts that way so you might want to be specific about how you think positive. You might find something like, 'I expect the best to happen. my mind is focused on the good that I seek.'
