As someone who's been immersed in a number of online industries for quite some time, I know a thing or two about what it takes to succeed in this arena. However, just like you, I started at ground zero with little knowledge, but a great deal of passion. What I learned along the way were some invaluable lessons from failure that hurt at the time, but helped immensely in the grand scheme of things.
Check if you need a model release. Photos of people can only be sold for commercial use if they've signed a 'model release' that gives you permission to use their image (children need a parent/guardian to sign). Without a release, these photos can still be sold for editorial use, as long as they were taken in a public place – eg, if you submitted a 'breaking news' shot with people in the background. If there's any doubt, always ask permission.
17. Amazon – Have you heard of FBA? It stands for “Fulfilled by Amazon” and it’s getting pretty popular. Basically, you buy products (in bulk is best) and ship them to Amazon for them to store. When your products sell, Amazon packs them up, ships them out and sends you the money (after taking their cut). There are people making a full-time living from FBA, while others just do it for some extra money.
Some of the best things in life are free and market researchers love to hand out new products in exchange for consumer feedback. If you like to try new products and have the opportunity to try them out for free, do some research and find the market research companies that offer products you desire to try. You can join campaigns and they will send the products or coupons to you to test them and provide feedback. You will generally have to fill out surveys and provide written reports based on your opinions. You will get to keep the products and they will sometimes even send you a monetary gift as an offer of thanks for doing the work.
