But that sounds elitist so nobody says it. Doesn't make it any bit less true.
Ones that let you hop in just whenever you feel like it and do one hour of work, with no commitment to minimum hours per week? And that you can put in a single productive hour every so often, without ramp-up time eating that entire hour with nothing to show for it? And that pays enough to make it worth it (i.e. not Mechanical Turk or whatever)?
I don't even know what such an ultra-flexible, low-context (= near-zero ramp-up time even if you only do it an hour or two a week, and some weeks not at all) but still high-paid gig would look like, or how to go about finding it.
Meanwhile, you can value-shop if you feel like it, or not if you don't. Entirely optional and no commitment or outside expectations. You can do it very seriously one week, then not do it at all the next.
There isn't a lot of daylight between low-paid, mostly uninteresting gig work and a real side job that takes some marketing, sales, avoiding time-wasting people who want to low-ball you, chasing payment, and some expectation of ongoing commitment.
I do have something drop in my lap now and then from someone I know, e.g. ghostwriting something. And that's fine. It's good money for maybe a day's work overall. But you can have tight deadlines and if you just wait for the phone to ring, you're probably not going to get a lot of that sort of thing.
I live in a city where multiple grocery stores exist within 5 minutes of each other and I do enjoy doing mundane tasks outside my professional life. Those tasks made me pause, clear my mind, and escape the bubble that we called "work" (yes, work itself is a bubble).
We have discount grocers nearby that sell a crap-shoot of stuff the bigger stores are trying to get rid of. If going there before heading to Wegmans can save me $50-100/month after gas, for maybe an extra 30 minutes - 1 hour of time, would be worth it these days.
C++ programmer by trade.
When I need to pad my savings I cut some costs but mostly I just work extra hours in side gigs. I couldnt imagine its worth going to multiple grocery stores to compare prices. Shop at 1 store, pay more for some items, work an extra hour to make up for it. I'm building my career and getting paid instead of experiencing traffic, grocery stores at peak hours, check out lines, and loading/unloading food to and from the car/house for a second time.
Does it really make sense for you financially to do that?
