Different people have different lifestyles. They do the same things from morning to evening every day.
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.
