If you're here, you have some part of a hustler's spirit.  You work hard.  You see opportunities and you seize them.  

And in this good year of our Lord Two Thousand and Sixteen, you also know that neither tomorrow nor jobs are promised.  You may be killin it at work today and let go in an unfortunate round of layoffs tomorrow.  

So you might have a side hustle.  Or you've thought about one.  Maybe you see your side hustle as your on ramp to a life of freedom and answering to no one.  Maybe you just need some extra cash to float you month to month.  Either way, as long as your side hustle is extra money, not your main source of income, you need to balance its demands and protect your main job.
