While having a formal background in graphic design is absolutely going to be helpful, it’s also relatively easy to learn the foundations of graphic design on your own. An increasingly easy-to-use Adobe Illustrator and even more easily accessible tools like Stencil and Visme are making it so that just about anyone with two opposable thumbs, a bit of creativity, and motivation can earn a side income doing things like designing (and selling) images like these motivational quotes that can be printed onto posters and sold on platforms like Etsy. Or you can find a local startup, small business owner, or photographer who could benefit from some extra help designing or altering images.
We’ve all dreamed about having a massive social media following and it’s actually much easier to achieve that you think. There are plenty of automated tools to help you grow, all you need to do is post consistently (that’s how I built my Instagram account to >10,000 users in 3 months!). Once your following is large enough you can begin to charge for shout outs, product promotions, etc. and drive traffic to a blog or email list.
I surprisingly get a lot of people asking to detail their car. I never intend to make a business of it, but I love doing it to my cars and people ask me to do it to theirs. All it takes is a cheap orbital buffer (mines a used craftsman) and a shop vac. I normally get easily $100 for a basic wash/wax/vac, or $200 to remove scratches and polish then wax the car.
