"Imaginary testing is unreliable, and in many cases, it's a huge waste of time and energy. In truth you just don't know what will happen until you try. You may start a business, and it could take off in ways no one could predict. Or it could be a complete failure. You could ask for a date and end up with the partner of your dreams. Or you could be rejected cold. It's great to visualize what you want, but you never really know what's going to happen until you act."
