Wishing

Do any of you guys know of anything, any tricks or magic, or meditation or hypnosis or anything, that would make a wish/want happen? There's something that I really want, and it's something that I can't achieve (i.e., losing weight, good grades, etc) but it's something that may happen at random (i.e., a random competition, drawing names from a hat). I don't want to give away what it is because then I am afraid that it won't happen. But if anyone can tell me something that I can do to help, I would be so grateful 💜
