Taking on a side hustle is often seen as a way to bring in extra income, but if you approach it strategically, a side hustle can do much more than help pay the bills. The right side hustle can build real, transferable career skills, the kind that strengthen your resume, open new job opportunities, and prepare you for bigger roles in the future.

If you want your side hustle to work double duty, earning money now and building career capital for later, here’s how to choose one that supports your long-term goals.
