Small and relatively unimportant things and habits should not go on the Todo list.
I usually write that i have to complete my fabulous routine instead of writing drinking water,excercise etc. Otherwise the other habits may include like oiling my hair,steaming my hair,completeing my homework etc.
Then my second to-do list is first thing when I get to work. I simply line out my goals for the day at work.
I consider these two lists very seperate and rarely do they intertwine. Hope this helps!
On Sundays I look at the whole week and map out my workouts and training for the week considering any hired work or travel. At the beginning of the month I always look at my month and I assess my whole year quarterly.
If you ever have questions you may ask!
I include basic tasks such as the ones you wrote above. I advise breaking down big tasks such as “studying something” to small tasks (“write hw”, “ schedule what I’ll do today” “do the thing”, “organize desk”).
I also advise you to write “eat breakfast/lunch/dinner/a snack”, “taking a shower” and such.
