I am a great believer in the OHIO principle: Only handle it once. When you read an e-mail, decide whether or not to reply to it, and, if you need to reply, do so right then and there. I have found that about 80 percent of all e-mails, whether internal or external, do not require a response.

From the law firm's perspective, billing by the hour has a certain appeal: it shifts risk from the firm to the client in case the work takes longer than expected. But from a client's perspective, it doesn't work so well. It gives lawyers an incentive to overstaff and to overresearch cases.

If employees need to stay late in order to curry favor with the boss, what motivation do they have to get work done during normal business hours? After all, they can put in the requisite 'face time' whether they are surfing the Internet or analyzing customer data.

Routinize the routine. The things that aren't important to you, whether it's breakfast or your commute, try to do them with the least energy possible so that leaves you with more energy for other things.

You have various institutions like law firms and accounting firms which bill by the hour. I'm really against that. You have an incentive to go slowly, be there as long as possible, to over-research things and over-staff.

Mandatory auditor rotation is designed to address a potential conflict of interest between a public company and its auditor. Because an auditor is hired and paid by the public company it audits, the auditor's desire to maintain a good relationship with its client could conflict with its duty to rigorously question the client's financial statements.

I'm used to being productive, ever since I was young.
