Be willing to risk picking a date even if you end up changing it down the line. Now creating budgets for yourselves make sense. From there, budget your household and personal expenses. Cut out magazine pictures that remind you of your dream and put them up on the refrigerator door. Spend some time together dreaming about your dream, getting ready for when it really happens, and so forth.
Dreams build upon each other.
Nurture and grow the closeness you will have created between each other in achieving your first dream by creating your next together-dream. Money is a means to an end. Nothing more, nothing less. The choice is yours. A Way of Life.
