Do you have things on your to do list that have been there for weeks? Months? Longer? If so, may I make a suggestion? Either do them today or take them off the list. If you haven’t done them by now, what makes you think you are ever going to do them? Plus, if they haven’t been done by now, they must not be that important.
Keep in mind that a to do list is not the same thing as bucket list of things to do before you “kick the bucket.” It might take a long time to accomplish some of the things on your bucket list. It’s good to keep that list to keep you motivated to accomplish those things.
A to do list is not the same as your long-range goals and corresponding plans, either. Those, too, can take a long time to accomplish.
However, for your daily or weekly to do list, I’m sure there are things that you can safely delete if they have been there far longer than a day or week. Clean up your to do list so that you can focus on the important items.
