To do this, simply associate the thing that you need to do (go to the bank) with a phonetic keyword for 1 (tie). Visualize the next thing that you need to do (pick up dinner) with a keyword for 2 (knee). When you wake up in the morning, you simply need to go through your keywords to remember the things that you need to do.
A variation on this method is to group your keywords by category. For example keywords 1-10 could be used for things related to work, keywords 11-20 could be for things related to home, and so on. This will help mentally organize your to-do list.
To reduce interference between days, you could use different keywords for each day of the week. Monday uses keywords 1-10, Tuesday 11-20, etc. Pick the method that works best for you.
