Of course you don't try to lose money, but you'd be surprised that it's not as easy as it looks. You'd be surprised how hard you have to work to not go under. I read this quote from George Gobel once and he said it best:
It took me thirty years to become an overnight success!
I've had many employees that left, thinking it was easy to do what I was doing. To a man they admitted later how wrong they were to think that.
I didn’t say it was easy.
I said you don’t enter a deal in which the numbers you’ve crunched say that you lose.
