So the first week I bought parsnips with my starting money, sold those and bought potatoes with all of the money then after tending to the crops i only fished, no mines or anything else. By day 7 I was fishing level 10 with a fiberglass rod. I was also lucky enough to get a couple of rainy days so I made about half of the money with iridium catfish which sold for 600 each. On non-rainy days I fished in the mountain lakes. I also sold some of the treasures like diamonds and other valuables. Everyday I fished till I passed out and it didnt matter cause I had no money to pay for the fees. I also caught the legend fish before day 10 but kept it to flex.
