If you're on the fence about a career change, consider this: 87 percent of career changers say they're happy they made the leap, and 65 percent report less stress, according to the American Institute for Economic Research.

Here are 20 great second careers that won't require you to hit the books too hard. The salary figures come from the Bureau of Labor Statistics.
REAL ESTATE AGENT
Average annual salary: $59,360
You won't need more formal schooling to help others buy and sell their homes, but in most states, you need to take a pre-licensing course and a licensing exam to get started, according to Realtor.com. Once you're official, joining a brokerage that is welcoming new agents is an essential step, but take note: You'll probably be paid by commission only, so get out there and sell, sell, sell.
Average annual salary: $31,110
Like kids? Does having the summer off sound appealing? Many districts are constantly searching for reliable drivers. The first step will be getting a commercial driver's license with a special school-bus endorsement, a process that requires you to pass a written exam, road test, and medical exam, according to DMV.org. A clean driving history is also a must. School districts will also likely require a background check.

A good library technician is essentially a librarian's right-hand (wo)man: You'll help patrons find materials, catalogue materials, retrieve online reference information, and perform other duties as assigned, according to the American Library Association.

Average annual salary: $67,760

One more thing: You're likely working on commission, not guaranteed salary.
Average annual salary: $42,780

After that, you'll need to decide whether you want to work at an established gym or studio, or go it alone building your own client base.

HOME HEALTH AIDE
Average annual salary: $23,600

Average annual salary: $73,160

COMPUTER USER SUPPORT SPECIALIST
Average annual salary: $53,100
If you're comfortable with technology and like helping others, a career as a computer user support specialist -- someone who helps others work through computer problems -- could be a good bet.

SELF-ENRICHMENT EDUCATION TEACHER
Average annual salary: $43,150
Got a passion for yoga? Gardening? Cooking? If you have deep experience in a non-academic subject that others want to learn, you can make a good living teaching them.

In some formal settings (for instance, teaching dance at a dance academy), you may be required to hold certain certifications or demonstrate your expertise.
Average annual salary: $43,590
If the open road feels like home, driving a truck could be your ideal second career. Forbes notes that it's increasingly common for new drivers to be over age 50.

MEDICAL RECORDS TECHNICIAN
Average annual salary: $41,460
If you're ultra-organized and discreet, a job managing health records could be an appealing career path.
