They say that Luck is the intersection of Preparation and Opportunity. I think you can start working on this goal now, in little ways. Maybe as simple as grow a few tomato plants or make jam with strawberries from the farmer’s market. By the time you have your land, you will have many skills under your belt, allowing you time to learn the many more that you will need when you kick this goal into high gear. Many blessings on your journey!
