3. Embrace frugality, starting with your closet.

When professionals start earning money in their 20s and 30s, they often start spending it, too. That's where Grillo thinks women go wrong. "They're making six figures, and they're spending all of it on Guccis and Pradas and dates with guys that don't care about them, and they're not investing," she says. Instead of splurging on shoes and dinners out, she wants women to save their money, and to invest it.

4. Save at least $5,000 per year per family member.

"It's not how much you earn; it is how much you save that determines your overall wealth," Grillo writes in her book. She acknowledges that for people like her who had their careers derailed by the recession, getting back on track is no easy task. The only way to build up savings is to live below your means, she says, and that might mean bringing your lunch to work, doing your own cleaning and eating at home more. She suggests saving at least $5,000 per year, per person.

5. Think like an entrepreneur.

Whether you're a lawyer, doctor or hairdresser, Grillo says everyone has to act like an entrepreneur, which to her, means acting like a leader. "At the end of the day, you have to be someone who makes a positive contribution to the company over what you're costing them. That's your brand. If you're thinking you're going to work to just pass time and the boss likes you, you're wrong," she says.

Got that, ladies? The world doesn't always make life easy – and that's why you have to be tough and rise above the inevitable setbacks.
