It is becoming more necessary every year to continue your education through your adult life. Even if you have finished with your degree, there are plenty of useful classes offered either at the local community college or high school. Beyond the ones that would benefit your career, you may want to look into classes on critical thinking, constitutional law, fundraising or evolution. They are also a great way to meet new friends and contacts.

If you are in a position to teach a course that would benefit Freethinkers, you could make a little extra money by teaching adult education courses. You can polish your skills by speaking at local Freethought meetings or try Freethinkers Toastmasters first.
