Related to that are changes in your industry. A classic example comes from a century ago when ice was harvested from lakes and shipped to warmer climates. But with the advent of affordable electrical refrigeration around World War I, that business pretty much disappeared. Likewise, any layout artist who used only 1990s-era software and refused to learn anything else probably went out of business years ago. But reasons for a change in focus aren’t always so negative. You might uncover an opportunity in data entry jobs that’s just too attractive to ignore even if that means abandoning your old line of work.
First, let’s get the obvious differences out of the way of freelance work. Writing is done inside, it isn’t very physical, and it can be done anywhere. Horse instruction is the opposite. It takes place outside, it’s physical, and it’s not portable at all. Besides differences in the type of work, the business aspect also differs quite a bit. While you’ll tend to have corporate clients as a writer who in turn will re-sell your work to readers, you’ll be dealing directly with your service’s consumers as a horse instructor and the expenses are very different.
