Jason Fried reveals how he got good at making money. I am not a full-fledged member of the Church of 37signals, but one of my favorite lessons from them is that a business needs to practice how to make money in order to get good at it…it’s not something that you just turn on when monetizing mode strikes.
So here’s a great way to practice making money: Buy and sell the same thing over and over on Craigslist or eBay. Seriously.
Go buy something on Craigslist or eBay. Find something that’s a bit of a commodity, so you know there’s always plenty of supply and demand. An iPod is a good test. Buy it, and then immediately resell it. Then buy it again. Each time, try selling it for more than you paid for it. See how far you can push it. See how much profit you can make off 10 transactions.
Start tweaking the headline. Then start fiddling with the product description. Vary the photographs. Take some pictures of the thing for sale; use other photos with other items, or people, in them. Shoot really high-quality shots, and also post crappy ones from your cell-phone camera. Try every variation you can think of.
