You get to read and write all day.
Workdays can be spent in pajamas, or in your garden. Or both.
You can spend hours in a bookstore and leave with lots of new books. It's research. It might even be tax-deductible. Have your cake and eat it, too, and then have more!
Interesting people who have written interesting books are willing to meet you. They may even want to meet you.
Same goes for interesting people who have been written about in interesting books. Even better.
Spending time in your adopted language's country is also considered research. Travel is encouraged, if not required.
There isn't enough time in the world to read everything you want to. But you have a good reason to try.
