Tell us a bit about yourself.
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 a major challenge you had to overcome to get to where you are today?
I suffered a back injury. Doctors prescribed me a large amount of oxycodone and fentanyl to cope with the pain, which is incredibly easy to get addicted to. I was determined to not get caught in that trap, so I quit cold turkey. I truly believe that you can accomplish anything with the right mindset.
If you could start over, what would you do differently?
I wouldn’t wait until after college to start a business. I could’ve been where I am today a lot sooner had I gotten a jump start on my career.
