Hi, currently, I am studying for an examination, and I believe I have developed a bad habbit of going to bed very late. Concerning the exam, there is still a lot to study for me, but I think I am doing well and it's not too stressful so that I can relax if I want to. In these days I do hardly go to University as I study at home instead. In the mornings, I wake up between 10 and 11 and then don't feel much like working. I usually start at 12-13 o'clock in the afternoon. But I am usually not that efficient and I take a break usually from 17-18 or to 19 o'clock. It is then that I become really efficient and it's the evening time when I become really good. I usually work to 2 or 3 in the morning and then go to bed. My parents hate it, but usually I feel best in the evening/night and when I see that I have only three or four hours remaining till 2 or three o'clock (bedtime), I really try hard and feel like I don't want to let the day go. Usually, I manage to get ahead a lot in the evenings, my peak is around 22:00 I would say. I sometimes wanted to change that pace and go to bed earlier, but the feeling that I don't want to let that day go without finishing this or that chapter always makes me go on till 2 or 3 in the morning. Is that a bad rhythm/pace? Should I absolutely change it? What do you think?
