To gain at least 1,000 gold every day in summer, you don't have to grow crops or harm your stamina mining. Just collect grasses. Each grass pays at least 100 gold. collect three in three different places(the hot springs, by the lake mine, the woods by the wood cutter's house, and the beach). do this daily and collect 1,000 gold a day. This hint best works in the summer for there are more grasses grown in that time.
