No dream is impossible! A 10-year plan is not a bad idea, but leave some wriggle room for adjustments to the plan. We had a 10-year plan for our homestead. We are into year six and I think we may extend the time frame just a little. Sometimes certain phases of construction take a little longer for various reasons; weather, availability of materials and of course costs rising exponentially. But dreams do come true and we are eating our own bananas!
