Here's how it goes:
Go to church on Easter Sunday morning. Be alert and pay attention. When the priest (or whoever is leading the service) announces, "Christ is risen." Immediately shout out loud something like, "I've got an ace!" or "I have a full house." or whatever it is that you need. Allegedly whatever you call out will be yours for the year.
Presumably this will work for anything you might shout out, including: "I am awesome." "I have an A on my exams." "I have the winning ticket!" or "Everybody loves me!" etc
