Melanie Duncan is a serial entrepreneur who, along with her business partner and husband, Devin, has been experiencing success since college. While studying, they started Custom Greek Apparel, an online store offering sorority and fraternity members apparel with customized colors, fabrics and embroidery. Next, they launched Luxury Monograms, offering custom monogrammed home decor items. Soon their products were being featured in magazines and on Good Morning America, the Nate Berkus show and more. When Duncan’s businesses were well-oiled machines, she decided to jump into the online education space, offering classes and support for makers and small business owners selling physical products. Now she has had over 160,000 students go through her training programs, she’s consulted on digital strategy for major corporations, and spoken on stages all over the world.

I caught up with her recently in New York to ask her what she believes led her to such massive success, and what other makers and online entrepreneurs can do to follow in her footsteps. Here were her best tips, found on Entrepreneur.com.
