DailyFinance.com recommends considering a downloadable application if you have a smartphone. While it might be a big difference from updating a physical document every week, it's more convenient and you'll always have it with you on the go.
Another option is to download software to your computer where you can calculate your finances and keep track of how much money is going in and out. A program as simple as Microsoft Excel can give you an opportunity to do the math without spending an ample amount of time scribbling into a checkbook.
If you're worried about the future of your finances, consider speaking to your psychic. During a live psychic reading, you can find out if switching to a new money management system will benefit you later down the line.
