Take role of a young farmer who has one big goal. He wants to grow his farming business, and become rich. As you harvest your first crops, you realize that this will be a long run. You do not have enough money to buy all those fancy and expensive farming vehicles that would make your life easier. You have just one tractor, and that is it. Work hard day in, day out, and first success will come. Sell your first harvest, and invest your money into better vehicles, or buy equipment like plows, or trailers.
