Can it be that I have overlooked something, that there is something which I have failed to understand? Is it not possible that this state of despair is common to everyone?
As a general rule never take your whole fee in advance, nor any more than a small retainer. When fully paid beforehand, you are more than a common mortal if you can feel the same interest in the case, as if something was still in prospect for you, as well as for your client.
