Just start pounding the pavement, that's really all you can do. Quitting smoking will help - maybe start chewing gum? I never got into smoking, so I have no point of reference for what that'd be like. I know hindsight's 20/20, but in the future, the minute you decide to take a written test you should probably start preparing for the PAT, and continue to get into better shape. Good luck!
When you wish upon a falling star, your dreams can come true. Unless it's really a meteor hurtling to the Earth which will destroy all life. Then you're pretty much hosed no matter what you wish for. Unless it's death by meteorite.
