Why did you start a real estate business and not some other type of business?

[Larry Turowski]

Do you just love real estate?  Or, like me, do you just like business in general?  Was it the "glamour?"  Or was real estate simply the vehicle to financial freedom?

For those of you who have or are making this a business, not just a hobby, why real estate?

I thought of this question because I was just perusing, since I never completely read, this article, How to Start a Startup, by the president of Y Combinator which has launched 725 startups.  Of course, my mind went back to several episodes of Shark Tank, a show I really enjoy.   I'm generally interested in business and there are other opportunities I'd enjoy pursuing in the future.  I know my reasons for pursuing a real estate business right now.  What are yours?
