So much of the pain in life, over time, is caused by distance from the truth. And the same is true in business.
Ask these questions of yourself, and try hard to answer them honestly. If the news is bad and you deal with it like an adult, I promise you'll live to fight another day. If the same is true but you're a good enough salesperson to sell yourself eventually you're going to hit somebody else's wall, and create collateral damage you might otherwise have avoided.
There's a fine line between being the captain of your destiny, and the prisoner of your own wishful thinking. Use these questions to help sort out which side of it you're on, and please share what you learn with the rest of us here.
