Tips for New Players
Things I Wish I Knew When I Started Playing Stardew Valley
Don't sell things unless you need the money. Storage space is relatively cheap, so make a bunch of Chests and store at least a few copies of everything in the chests.
Craft foraged goods into seasonal seeds instead of selling them. Money is rather important early in the game (and seeds are also expensive). Converting Wild Horseradish, Daffodil, Leak, and Dandelion into Spring Seeds is worth about 12.5g per crop and provides more revenue than any other crops besides Strawberries and Coffee Beans in the Spring.
