All of my money was in stocks (which I've sold off) and online Savings Accounts since college. INGDirect.com and EmigrantDirect.com had the best rates. And because I have always been a pretty good money manager, my credit has stayed pristine. Last year I took the full line of credit from my oldest card (an MBNA Mastercard I applied for freshman year at UCI because they were giving away a CD case) at 0% interest and placed it into a 9-month Certificate of Deposit at 5%. While the money earned interest, I was required to pay a high minimum on the balance of the card. But in reality, I was actually forcing myself to save. Example: I borrow $10,000 from my credit card at 0% interest. I put it in a CD at 5%. I have to pay 1% of the balance (or $100) on the card monthly. After one year, I make about $512 on the savings account but I only owe $8800 on the card. The $1200 in payments I made are savings. The whole transaction nets me $1700. But I was working with much more money than that.
Which brings me to tax season. You pay tax on interest earnings. Fortunately, I have a side business in video services called Filmgeneration. I don't make a lot of money as it's usually just gigs I pick up through friends of friends. But I do put a lot of money into it and I am able to file a Schedule C and write off my expenses.
Once I've plowed through my savings (I assume Western Europe will take care of this pretty quickly) I will rely on credit cards and begging. After people ask me how I'm paying for this trip, they usually ask me what I'm going to do when I get back. I answer, "Working to pay off the trip".
Oh, and I'm selling stuff left and right. Anyone want an IKEA PS sofa bed? It's blue and really comfy.
