In this episode, Jack opens up about his childhood in Germany where he learned to not be afraid of hard work, although he didn't have many entrepreneurial tendencies there.  

Upon coming to America as an exchange student, he obtained his MBA and met his wife - who is also an immigrant from Honduras.  Over time, and after working demanding and draining 80+ hour work weeks, they began investing in real estate.  

They made many mistakes.  They also were able to use a piece of commercial real estate to fund his mother-in-law's retirement.  They got into big land deals, tax liens and continued learning as they built an empire.  

Now, they teach others the trade and travel at least three months per year!
