For example, the task of making a trip to Ireland requires saving money, arranging time off from work, getting my passport, etc. The task of tracing my family's Irish roots requires learning about genealogy, talking to close family members, writing letters, visiting libraries with genealogy collections, etc. Arrange those steps to make a procedure that leads up to completing the task. Perhaps you can stop buying sodas and put the money into your Ireland fund. Or perhaps you can stop by the library and get a book on genealogy.
Every goal starts today.
By breaking the goals down to daily focused steps, your huge future goal become manageable. And as you do each step, you can visualize accomplishing this bigger goal, which can help keep your morale high for the journey. If you find your enthusiasm waning, feel free to redefine your goal. Perhaps that item was not as important as you thought. Since these goals are for you alone and not dependent upon the actions of others, you can always change focus or redefine at any point.
