A second language
Depending on the job, knowing another language can set you apart from the competition. In certain careers such as customer service or sales, a second language can increase your value as an employee or help you drive sales. This can result in higher pay and better promotion opportunities.
You can also use your mastery of another language to earn extra cash by tutoring or offering translation services. Tutors can earn anywhere from $25 to $100 an hour, making this a lucrative side hustle.
Check your community college for in-person or online class options. To brush up on your skills or start learning a new language, check out Duolingo for free lessons. Ready to get certified? The University of Wisconsin-Madison offers a six-month Business Spanish Certificate program starting at $720.
