Ah, yes – the freedom of being a freelancer. The carefree life of the consultant. The pain-in-the-ass clients who pay late.
With the exception of ravenous otters gnawing on your extremities during a dip in the ol’ swimming hole, nothing sucks more than waiting for an invoice to finally be paid. Sure, patience is a virtue. And politely standing by without making waves will maintain a good client relationship.
