ABC List
To-do list lovers, this one’s for you!
Start by writing down your to-do list.
Then identify the categories your tasks fall into (e.g., “work,” “self,” “house,” and “family”). Give each category a letter code, (e.g., W, S, H, and F). Write this code next to each to-do list item in this category.
Within each category, rank the importance of each task (e.g., the #1, #2, and #3 work tasks, and the #1, #2, and #3 self tasks). Write this ranking next to the category code of each item, so you end up with W1, W2, W3, S1, S2, S3, etc.
Use these categorizations and rankings to help you see what’s most important and choose what to do when (e.g. maybe it’s W1, S1, H1 or perhaps F1, F2, S1).
