Some alternate takes. As usual, everything will eventually work, just a question of how fast and how you feel like playing.

• Talk to people if they’re nearby, give the best birthday gifts you can for 8x effect (regular quality loved > high quality liked > regular quality liked, but even “neutral” gives some boost).
• Scythe weeds, plant mixed seeds. You can wait for a scarecrow if you like, I prefer to just plant right away and get almost as much money a few days earlier.
• On rainy days, fish (mainly early for early money). Or if mining, focus on downward progress and resources on good luck days, combat (but not getting knocked out) on bad luck days.
• Get Caroline to 2 hearts, visit her tea room and get a cut scene, then the next day a recipe for tea bushes. Dump most of your spring seeds into those, then sell the bushes themselves for lots of early cash (you can plant a few for long-term).
• Sprinklers = free watering. Regular = meh, quality = good, iridium = great but those take a while. You may prefer to spend early iridium on crystalariums for jade for staircases for more iridium.
• Kegs/jars = free extra money in return for waiting a few more days. Hops + enough kegs = lots of money (literally almost 100x return on investment), but “enough kegs” takes some time to build up (plant and tap oak trees early).
