I've been trying to get a better handle on my finances and I keep hearing about how important it is to track personal expenses. I'm thinking about setting up a spreadsheet, but I'm not really sure where to start or what categories to include. What kinds of expenses do you track in your spreadsheet? Are there any tips or templates you'd recommend for someone just starting out? Also, how often should I be updating it to ensure it's effective? Any advice for avoiding common mistakes with this kind of budgeting tool would be appreciated!
