Budget the obvious things first
Start with two or three Regular categories: groceries, transport, subscriptions, rent, utilities, or dining out. These repeat often enough for a target to teach you something.
Make the number useful, not heroic
If groceries are normally around 280, a first target of 300 is more useful than setting 200 because it sounds virtuous. A budget should help you notice reality sooner, not punish you for having one.
Let the plan change
If a target feels wrong after a week or a month, edit it. That is not failure; it is calibration. The useful question is whether the new target better describes the life you actually want to plan for.
A budget is not a promise that life will behave. It is a comparison point that helps you notice what is happening while you can still respond.
