Memories- Time management sheets

I can't remember when I was this particular about my time management during schooling! I'm impressed by my teen self. I'm sure I have done this in high school. I'm not sure if I have tried out this in 8th class. I'm happy to see this paper after ages. 

Looking at these papers, I'm making it a habit to add a date in whatever piece of paper I jot on. Just to help me to feel nostalgic in the future relating the writings to dates and memories.
