What’s your background?

I’m a 7-figure entrepreneur, investor, speaker, and author. I’ve got three books out: 8 Unbreakable Rules for Business Startup Success, The Greatest Entrepreneur in the World, and World’s Greatest Business Plan. I also host my own podcast. 

What was the biggest rejection you faced and how did you overcome it?

Right after having a newborn and buying a house, I was fired from my dream job. It happened out of nowhere. I had no backup plan at the time, so it was incredibly stressful to suddenly be unemployed. From that day on, I decided I would never depend on someone else for my paycheck.

What accomplishment are you most proud of?

I’m proud of the businesses I’ve started. Many have been more successful than I ever could have imagined, and those that weren’t made for great learning opportunities. I’m also proud to have written three books so far. A lot of people say they’ll write a book someday, so I’m proud to have actually done it!
