We know that bad clients produce bad returns. What many don't realize though, is that "bad returns" can actually mean negative returns with some customers. So trust your instincts when dealing with questionable people. If something feels wrong, it probably is.

Also, please beware of the other type of "negative return" customer, the mercenary shopper. This is the person who cares only about price and continues to shop you before and after they signed a lock agreement. These types of people either don't see or don't care about the value in your services. They will be hard to please at every turn and they are more likely to complain about you to their friends than sing your praises.

So take in all the business you can, but remember that being somewhat selective about who you work with will always pay dividends in the end!
