" Are key to getting consulting work is to focus on a skill that you have. That companies use to only infrequently. To have in house right now themselves when it's too expensive for them right now. That's from Richard Greenwald of drew university in New Jersey. And I've never heard starting a business put from exactly that perspective it's different. Rather than thinking about the biggest volume client you can find. Think about somebody who could use your skills. Infrequently. To occasionally. That's how businesses grow. He also says the image of a consultant. Toiling alone from home is outdated many share modern -- suites. And work as teams and them function like a small boutique firm.
