I learned about this "Rule of Four Days" from an advocate practising in Gujarat High Court.
He followed this Rule strictly. If a client has to meet him, he has to take his appointment Four Days in advance. Otherwise he may refuse to meet him for conference.
He used to prepare all his cases "Four Days" in advance of their possible date of hearing.
In breif, he used to plan his life "Four Days" in Advance.
This is a bit difficult. Clients come at uncertain times. They ring at uncertain time. The cases in almost all courts are mostly called out for hearing at uncertain time, when you may be least expecting it.
Whatever may be our excuses, I saw this Advocate actually living by his "Four Days Rule". It cannot be said that this Rule is impossible to follow.
Perhaps, he may be relaxing Rule at times. With some flexibility, it may be possible to follow this Rule.
This very same Rule, I have seen in practice of a consulting physician in Delhi. If you want to consult him, you have to seek his appointment Four Days in advance. Otherwise, he will not meet. So Four Days in advance, he can see list of patients whom he may see after Four Days.
Basically, this Rule is about Planned Living.
