If you really have faith in your idea, even if no one else does, and you go in with your eyes open knowing you may lose, then – charge! On the other hand, keep in mind that the true entrepreneur marries goals and objectives, not isolated ideas.
When one of your ideas does prove itself unprofitable, don’t try to raise the dead; move on to the next method of achieving your goals. The entrepreneurial graveyard is full of corpses of exhausted individuals so emotionally married to a bad idea that they marched stubbornly on to starvation. Persistence in and of itself is vastly overrated. Used in proper context, persistence is a virtue. Glorified and adhered to without qualification, it is deadly vice.
