You need to agree with your boss about what you need to get done that week, what are the metrics of success. Sometimes you need more hours, sometimes you need fewer hours.

It's 5 P.M. at the office. Working fast, you've finished your tasks for the day and want to go home. But none of your colleagues have left yet, so you stay another hour or two, surfing the Web and reading your e-mails again, so you don't come off as a slacker. It's an unfortunate reality that efficiency often goes unrewarded in the workplace.

The most important thing is to talk to people that have jobs that you might like and to see what they say the job involves.

The classic problem as an entrepreneur is that they have a hard time delegating. But that's really crazy. Recruiting other executives is critical, so is dealing with customers and dealing with regulators. Those are functions that only the top founders can do.

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.

We don't take a macro view... We'd look at every company to figure out if trade sanctions are helpful or hurtful.

Wall Street is at best ambivalent. The size of the accounts is nothing big. How many Wall Street firms do you know that are running after people with $5,000 accounts?
