How do you avoid going over budget each month?

I know consistency is more important than having a perfect budget. I review my spending regularly, set realistic limits, and adjust as needed instead of trying to stick to a plan that's too strict. I also try to leave a bit of room in my budget for unexpected expenses because something always seems to come up. It's not about being perfect. That approach has helped me stay on track without feeling overwhelmed. What works best for you?
