Most to-do lists are wish lists. They contain everything you hope to do, not what you will actually do. This creates overwhelm. You look at the list and feel behind before you even start.
Try a different approach. Each morning, write down one thing you must finish today. Not three things. Not five things. One thing. This becomes your only goal. Everything else is optional.
When you finish that one thing, you have succeeded. The day is a win. If you do other things, that is bonus. But the day does not depend on them. It depends on that one thing.
Choose your one thing for tomorrow. Write it down. Put it somewhere visible. Then notice how much more likely you are to finish it when it is the only thing on your list, and how much less stress you feel when success is defined by one clear goal.
