"I don't care how good of a manager you are...you can't manage ZERO to a profit." Jim Watkins
For as much time as we spend talking about value propositions, brand position, messaging, social media, etc. the fact remains that REVENUE (for most that means Sales) is the first key, without it any business will fail.
Of course, like building anything there are essential steps and you don't improve by obsessing about the goal, but instead by taking action steps that move you toward the goal.
Nonetheless, it is a good reminder by my dad that, in business, REVENUE is the first goal because without it all the other stuff is pointless.
