Amazon: Many people don’t realize that Amazon is a haven for third party sellers, including regular Joes and Janes cleaning out their attics and garages. If you plan to sell more than 40 items per month on Amazon, consider registering as a professional seller. You’ll need to pay a $39.99 monthly subscription fee, a referral fee that usually ranges from 6% to 20%, and a $1.35-per-item closing fee for media items. You won’t pay the $0.99-per-item selling fee, however. Alternatively, register as an individual seller. The fee schedule is the same as for professionals, except you do have to pay the selling fee and don’t have to pay the subscription fee.
Walk around your neighborhood or town and I’m sure you’ll see tons of great local businesses with terrible design. However, with increasingly easy-to-use tools like Adobe Illustrator, Venngage, Stencil, and Visme, just about anyone with a creative mindset and a good amount of motivation can start making money online by being a graphic designer for local companies.
Regardless if you need to earn some fast cash or we're just talking about making money in the grand scheme of things, there's an important psychology that needs to be mentioned before getting into the strategies. If you study Freud's model of the mind, you'll discover the Psychic Apparatus. It's the three-part construct in your mind that controls all of your behavior.
