Hello Mystic Coaster and Welcome to the Forums!
If you have Caroline to 2
then enter her Tea Room (back door in her kitchen) on a sunny day and enjoy the totally normal everyday cutscene that could not possibly be hallucinated or induced with mind-altering substances. You will get a recipe for
the Tea Sapling the following day. They are cheap to make and sell for a
lot. Make a bunch and sell and you'll be rolling in g. If you don't have Caroline to 2
yet then Spring is around the corner and you can Forage Daffodils and Gift them to her to get those
up in no time. Talk to her every day at that helps too. Save your Fiber (so Scythe those Weeds!) in the interim which you'll need for crafting.
I found that to be the easiest early game way to make loads of g for all my nefarious uses.
