If you can perfect just one business, then that can open more doors for you to start more businesses. For example, if you’ve done something remarkable such as buy enough real estate to the point you no longer need a day job, then you can quit your job and just run your real estate business full time. However, you can also create another business out of that former business.
Being that you quit your job by investing in real estate, there’s a market out there for others who are looking to do the same. You can create another business (assuming you have your real estate business on autopilot and it’s not as demanding on your time) consulting others how they can copy your steps. The information and experiences you gained can be sold online in the form of eBooks, coaching, webinars, and in-person seminars to name a few.
