Thank you for your reply. I found it very profound and insightful.
So when a person who is fully employed might in addition have one or two other activities that they use to fill up the rest of their time, a person with no job might have to come up with 10 or 15 other activities. I can get why that might seem daunting... the can be a lot of mental overhead just deciding what you want to do, and then some overhead around organizing that time and keeping up with your various activities. So I can see why that might be a little off-putting as well. But to me, I think it's worth it. And with a larger amount of smaller things that you do, it's probably easier to stop doing one and find something else if you decide you're tired of it. Much easier than changing jobs, at any rate.
