Do you prefer to do this in the morning? Or to prepare it the night before?

I try to do it in my free times. I have chosen a schedule which has both night and morning tasks thus i open it at intervals to tick off things from my to-do list.

I prefer to prepare the night before because I am a night person. My mind just works better and I think more clearly than in the morning that I am half asleep and more likely to forget something.
