Freelance work generates an astonishing amount of non-work: invoices, chasing invoices, contracts, quotes, tax filings, three emails to arrange one call. For a long time I did this whenever it appeared, which meant it appeared constantly and I was never fully doing anything.
The rule
Two hours a week, Tuesday afternoon, all of it. Nothing administrative happens outside that window unless someone will lose money.
Things that arrive on Wednesday wait six days. This felt reckless for about a month and then felt obvious. Almost nothing is urgent. The things that genuinely are urgent announce themselves clearly and get an exception, and there are maybe four of those a year.
What it costs
Tuesday afternoons are unpleasant. There is no version of this where the admin becomes enjoyable because it is batched. It is two hours of tedium, concentrated, and I have never once looked forward to it.
Some clients notice the reply latency. One left over it. That was a fair trade, and I say that having done the arithmetic on what he paid.
What it buys
Four uninterrupted days. Indexing is work you cannot do in twenty-minute fragments — you hold a structure in your head and every interruption drops it. Before the rule I was doing maybe three good hours a day. Now it is closer to six, and I finish earlier.
The unglamorous truth is that most productivity advice is about starting. This one is about the far more useful skill of not starting — of letting a thing sit visibly undone without it costing you anything.
