Calendar vs. to-do list
Calendar. For things that happen at a certain time — like a doctor visit at 2:00 or work at 9:00.
To-do list. For things you need to get done, but not at an exact time — like 'do laundry' or 'call mom.'
How to add an event
Step 1. Open your calendar app or paper planner.
Step 2. Pick the day and time.
Step 3. Write what it is, like 'Dentist.'
Step 4. Set a reminder so your phone alerts you before.
Keep one list, not ten
It helps to keep all your tasks in one place. If you write notes on many papers, they get lost.
Pick one spot — one app or one notebook — and put everything there.
