Perhaps, having a planer can help . I use a small pocket one. You can plan ahead and organize according to your schedule. The to do list, I will say to review it multiple times during the day to get everything done, and most importantly always make time to breathe, and meditate this can help to do everything more efficiently
Yes! Break the list into sections, home, work, family, etc. Or urgent, soon, whenever. Then you can focus on the priority without feeling swamped. And any progree is good progress.
