Make Room For What They Can Handle
When I graduated from college, I received a job offer. The offer was to pay me nothing unless I made a sale. In hindsight, I am unsure how I decided that was a good idea or why no one didn't advise me against it.
The pitch was that every year, you would wake up with no base salary but the potential to earn as much as you wanted to based on how he does, how good you are, the caliber of your clients, etc.
I ended up being rookie of the year nationally, so it turned out okay, but damn, that was one hell of a way to start my professional life.
