No matter what skill path you decide to follow, doing repetitive actions to gather resources, and then processing them into something more valuable is pretty much how you make currants. If that doesn't appeal to you, I'm not sure how you made it to level 24.
Judging from other similar threads, it is actually quite common to get bored with the grinding when you are level 20something. Personally I have settled for harvesting and cooking enough for donations but not making a lot of money right now. Hope I won't regret not being rich when housing upgrades are released.
Anyway, I think one of the least demanding ways to make money would be to snipe auctions for cheap goods with the script and then sell to the tool vendor when inventory gets full.
You have 12 piggies apparently, you should get several more meat collectors to fill up while you are away. Also milk collectors and lots of butterflies.
If you had different kinds of trees in your garden you could harvest them once a day with little effort. Growing vegetables in your plots is a bit repetitive, but you can sell potatoes and cabbage for currants and it is not that much trouble to grow them.
Brewing Hooch is quite good. Fill the hopper and get 35 Hooches to sell each time.
Gardening and caring for trees and animals is good for rewards like Musickblocks which you can auction, donate, or sell for emblems and currants.
I like to vary my activities from day to day, not so boring then as doing the same thing all the time.
Making currants is pretty much a side effect of doing most things in game, they aren't all that useful once you've got past housing costs tbh...mining I also find pretty dull, so getting your AK skills up and then running around nibbling every pig that moves can be a slightly less dull way, at least it gets you out seeing different parts of the world. With the right skills, in a run through a couple of regions you can make 20k in meat and maybe the same again in music blocks from squeezing chickens/gathering from trees, plus you've also then got a load of stuff to make other things with...
If you want a project to work on to make a lump of cash, making butterfly eggs (lots of bubbles, buy a bit of honey), huge amounts of expensive food, maybe Meat Tetrazinnis in the hundreds daily, (gather pretty much everything, everywhere, get up to MC2 to save energy), then sell to the tool vendors or auction if the price is right...
Accumulating stuff that's worth a lot and then donating it for XP and then leveling is maybe a way to make it less dull, just sell a little bit now and then to keep you going...
but you won't get away from having to grind a little bit to make some cash.
Aside from buying a house and tools and toys, what do you need currants for?
I grab the quoins when I see them, don't spend much, and it's piling up.
I can also squeeze chickens, milk butterflies, and nibble piggies until there is a full bag just wandering around Ur for an hour or so, then donate it for favor and extra learning speed. I could sell it I suppose.
Animal Kinship VI and VII are much more interesting than mining and can easily make more in the same time period. There's no competition, either -- only pigs stop providing nibbles and even there it's rare and you can feed 'em a single zucchini to get them to produce again -- so you're not constantly running around trying to find that recently respawned sparkly rock.
harvesting the woods in buckward vale quarter alone are worth 1200 currants a go.
oops, sorry. one was not properly dusted and i accidentally killed it.
so slightly less. but if you also harvest the beans and fruit and pigs and chickens, well, you get the idea...
ETA: wood tree harvest of marrakesh meadow quarter will bring 1200.
harvest of marylpole mount woods doesn't even yield enough to be worth selling.
you can get 2400c from harvvestign woods at broxhurst green quarter.
a quick harvest off of the woods of lorme rush quarter are worth 1600c.
vuos bosca woods will get you 2400c. it takes a little longer because of the layout of the neighborhood, but it's very rich with other resources and you can make a bundle off of those, so take your time. don't forget to feed the pigs while you're there.
it is such a nice neighborhood i might consider moving there, which is saying something since i love groddle meadow.
You can also run through the desert, collect gems and such from the dust traps, and sell those. I tend to alternate between that and mining to make currents, because dodging Juju bandits is a lot more exciting than mining most days.
I make my money from my 4 meat collectors and having a meat fountain, also from music blocks and pretty much anything i get from trees. I mostly mine for elements but when i get a diamond or ruby i sell. Remember to sell to the tool vendor they pay the most from all vendors other than maybe auctions if you have the patience.
Gathering from trees is a more interesting way to gain resources because it means you have to keep exploring. It also automatically keeps your mood up.
I like harvesting from wood trees because unlike other trees they reward you based on the number of branches, without caring about your gardening skills. They are a goldmine for new people compared to other trees. Even when I was getting one cherry per harvest, I could get 80 wood planks from a 4-branch tree. You get 320c from Tool vendor for 80 planks. If the tree has 3 branches, you get only 60 planks, and so on down to 20 or 25 for Harvest and clear, which also kills the tree. You can buy Fertilidust Lite at AH for about 180 a jar, which is 5 shots. (Don't get the more expensive Fertilidust, it does nothing more to a tree than the lite, it just does more trees at a time.) So it costs 36c to give a tree one shot, but each shot gives you personally 20 more planks, or 80c. So carry a jar of Fertilidust lite in case you find a wood tree (they are not common). It is financial sense to make every wood tree you find have 4 branches before you harvest, and then you are leaving something good behind for the next person who comes along. Don't worry, be glitchy. ((p.s. Edit: The wood harvest does not depend on your Gardening level. The musicblocks you get from petting and watering do increase as you go from G1 to G3. For other trees, the harvest as well as the drop is much lower for players below G3.))
I enjoy digging peat. While at it, I also scrape, scoop and catch Fireflies. One round through the bogs swells my purse and I enjoy the music, the sights and the Glitchen I meet while doing this. I also take a side trip to the Caverns to gather poo and collect quoins. I occasionally mine while there thus collecting some ores and gems. I make currants and have a very enjoyable outing.
I never have sold my crops but I have sold and donated the endless flow of Music Blocks that I get from Gardening, donating, etc.
Focus on something you like to do in the game, try to get a badge for it, sell all the excess byproduct. Expensive grilled cheese is fun, take a bunch of no no die over and over age cheese get rich.
