1. Create Digital Products That Keep Paying You

Got knowledge others want? Turn it into an e-book, course, or downloadable template. Whether it's how to budget, build a resume, or play guitar, digital products require effort up front but can sell for years with little maintenance. Platforms like Gumroad, Teachable, or Etsy (yes, even for PDFs!) let you reach an audience fast. The beauty? You make it once, and every sale after that is pure passive cash.
