You know when you have a stroke of luck, and the whole day's like that, you're on a roll? Think, 'Wow, what luck!', and you attract more of it. And it works the opposite way round too!
If I were you I would pick a name that resonates with what I DO want. Healthyme, Superman, Invincible, you know. The less energy you give to that nasty little bugger the better!
