Utilise sequencing to prevent lazy prioritisation, leaving you with desperately important unfinished tasks pending completion at the end of your day.
Most important task label
Photo - sequence task most important task 1, then second most important task, 3rd most important task
For tasks 3, 4 and 5? Revisit them after completing tasks 1 and 2. Don't be surprised if you then decide they're not pressing enough to warrant completion, or outsource/automate them. Tasks that hang off the bottom ends of your to do list have a habit of swelling in perceived importance, and are usually best to get someone else to do, or automated. But don't let them serve as fodda to avoid the important
Put a label (most important) on your 1 single most important task, sequence it first in your day.
Let this be the tip of your spear and organisation will fall into place after it.
