Most jobs require employees. The right employee gets the job done and an inferior one doesn’t do it right or leaves it undone.
There’s a spectrum of cost though. Employees require different levels of expense. If you use a cheap employee, you might end up with nothing. Use the right employee and you get the desired result.
Because the cost of employees usually fills out a linear scale from cheap to expensive, we can be lulled into believing the results are also on a linear scale. But that’s not true.
You’ll need to spend enough to get anything at all. Less than that is a total waste of time and money. Better to use an employee who costs more than you expected than to use a less expensive one and get nothing in return.
