201. John's Budgeting 101 Series #9: Monitoring
After making some decisions to adjust your expenses and looking for new streams of income, monitor yourself for the next few months, see if the decisions you made were effective.
If yes, keep it up and make those changes permanent.
If not, you may want to fine tune the decision and monitor again.
This is a lifelong exercise to make your income-expense ratio better. It takes time and there's no perfect solution or state. As you grow older, your income levels will change, your necessary expenses will change. If you get married, both income and expenses will change. If you have kids, also change. If you change jobs, get promoted, get a new line of income, more will change. So continue your monitoring and be flexible enough to change when required.
