For my daily productivity I have a system. The system works well for most of the tasks but for a long time I struggled following up with a certain type of tasks: the things I shouldn't be doing.
Those tasks could be marked done only at the end of the day as I wouldn't know earlier whether I will break them or not. That meant I'd need to remember such things until the end of the day if I did fail them. An unnecessary distraction.
For all tasks I have set a notification at eight in the evening if they haven't been completed by then. At that point it's still not too late to complete most of them. There I found the solution for my little problem.
When the notifications appear I usually dismiss those I know I wont be completing anymore for the day, or am unable to do anymore. I realized I could use this same method for those "not-do" tasks as well. Just set the alarm eight in the morning instead and let it be there until I either breach it or I'm ready to go to sleep or otherwise certain it won't happen anymore for the day.
