JOANN MAGUIRE, 75 |$50,000-$90,000 per year
Home: Churchville, Pennsylvania
Previous life: Schoolteacher
How she did it: I got my real estate license many years ago. After I retired from teaching, I took courses at a community college to get back up to speed. A realtor needs to be associated with a company, so I interviewed with a handful until I met the right fit.
What she learned: You can work as much as you want, and earn a substantial living.
What you need to know: Age is no handicap on this job. Age is actually a plus. I work with young families making one of the biggest choices of their lives.
