With all the pressure and tuition costs at all-time highs, many people are even beginning to question whether or not a college education is even worth the investment of time and money in the first place. And get this—only 24 percent of undergrads graduate in four years, according to the National Center for Education Statistics. That just translates to more debt and time.

So, how do you go about deciding what you want to do for the next 40 years? Here are 5 tips for how to choose a major in college:

1. Take an inventory of your natural aptitudes

Most people have two to three natural aptitudes that really drive their potential career success. For example, did you know skills such as hand-eye coordination and pattern memory could help determine your college major? People who have high sequential reasoning skills usually find writing and communicating in a clear and direct manner an easy task. Thus, a degree in communications would likely be a fit for someone with high sequential reasoning skills.

2. Ask yourself what you’re most interested in

Writing down your interests also helps when choosing a major. Just because you’ve always been a math whiz doesn’t necessarily mean you would enjoy a job in accounting if you don’t like being idle for long periods of time. By knowing your interests and exploring majors related to those interests, whether they be artistic, investigative, social, or otherwise, you are setting yourself up for an enjoyable career path.

3. Consider how you work best and recharge

How do you unwind? After a long week of school, do you like to go out with a big group of friends or settle in with a book and cup of hot tea? Maybe you’re a combination of the two.

Knowing whether you are an introvert, extrovert, or blended energizer will also help narrow down your choices when it comes to choosing a major. Teaching elementary school would most likely wear on introverts after a while, as they find it hard to be around large groups of people with no breaks for extended periods of time. Likewise, working alone for extended periods of time is difficult for extroverts, who recharge by being social.

4. Explore internships, externships, and job shadowing

A great way to really determine what you “want to be when you grow up” is to spend a day in the life of someone in the field you are considering. Visit your college’s career center to learn which local companies and organizations your school partners with in career exploration.

Interning and externing are great ways to make connections and figure out what suits your personality and work style in the real world. You may find you love your potential career and then again, you may hate it, but you never know until you try! Wayup is a great online resource for finding internships, and here are ten other sites that are great for finding internships.

In closing, heed this advice and keep in mind this Richard Yates quote:

If you don’t try at anything, you can’t fail …. It takes back bone to lead the life you want.
