Everything runs off the long-term money. Periodically, you’ll want to draw moderate amounts from your long-term investments to hold in cash (for immediate needs) and in short-term vehicles such as CDs (for emergencies). As money runs low to cover current and unexpected needs, replenish from your long-term source. Just remember to be moderate in your withdrawals from long-term resources. You want to take enough to have for, say, the next six to 12 months of current and unexpected needs, but you don’t want to draw down so much that long-term runs low or taps out early.
