You can today, prepare a better life for your future self.
In other words, looking backwards, that what we are today and have today, is the result of everything we chose, did, said, and even thought, in the past. So by wielding the power of preparation, we are able to influence our own future.
Example 1: Order that nice dress today, to feel better next week at that friend's party. (Prepare a great gift, so you make them extra happy.)
Example 2: Get that driver's license this year, to take that roadtrip in the mountains next year.
Example 3: Buy groceries on this windy/rainy day for dietary purpose, to feel healthier and lighter before year end.
