Social media is a tool, not magic.
If your service is crap or your product is garbage, no amount of internet smoke and mirrors will undo the damage you're doing to your own business.
You won't sell, you won't grow, you won't succeed.
Worse yet, you'll succeed for long enough to garner a large audience, and then, in a packed house full of people, you will crash and burn and they will boo and hiss and throw every rotten vegetable at their disposal at your until you leave the stage, never to be heard from again.
Creating a business you're proud of makes telling the world about it a natural, easy step.
Action item: Evaluate your product or service. Are your proud or embarrassed? Is it worthy of a great social media presence?
