Ha! Well, the good thing is that being an "expert" isn't only about having academic qualifications. Talk about your life experience. Say, "I was a real estate agent for 20 years and I learned..." That'll do it!

I, too, was a person that didn't go to college right away. I dropped out several times, but then I discovered summer classes and just got it done. I was 26 when I graduated and I went straight to Peru.
