James Clear (Jamesclear.com) has a host of ways to help make sure you focus on the importants like starting every day with the most important activities, and ruthless focus.
I spent a year organising my to-do list in these boxes and it was striking just how long the important not urgents keep getting moved on to the next list. Part of the secret there is to break them down to startable tasks rather than big projects. FWIW I don’t actually recommend the really concrete action of organising the to-do list in the quadrants. More being cognizant of what type each task is. But it may help for a while.
