Usually, they write their plans on paper. But sometimes they remember what things they will do in their minds. I also have my own lifestyle. it is wonderful! I get up early on weekdays, and do the school things then. But at the weekend, i never get up early. I sometimes stay in bed until lunchtime. One day, I stayed in bed very late. it was a weekday. The clock rang. It was six thirty. but I didn't't hear it. I stayed in bed until seven o'clock. I looked at the clock and jumped from the bed to the floor. I was afraid, “oh, my god, i will be late.” I shouted. So I didn't have breakfast. I put on my shoes and took a taxi to the school. i was in good luck that day. I wasn't late for school. I was pleased that time.
I think I should get up earlier on weekdays or i will be late. I believe you get up earlier on weekdays. Best wishes for you.
