What are the best tools you have used for organizing?

my iphone reminder app. i have a daily to-do list that reminds me of the basic things i hope to accomplish. in doing these daily, i hope to establish a semi-normal routine in all the current madness.

For organizing my time and my life I reduce my phone screen time and I go away from negative people do what I need I sleep good and wake up to watch my classes and do my quizzes even if I didn’t archive high marks but that what will make me learn in my future my old mistakes never been repeated and my now mistakes won’t be repeated
