Anyway, I think it depends on one’s body clock, which has been conditioned by sleep/wake patterns. I will confess, though, that getting 6 hours of sleep regularly (as a man in my upper 20s) leaves me more restful than 9. Interesting anecdote… I fell asleep for an hour or so a few evenings ago, tried to go to bed at midnight, but couldn’t sleep, and ended up staying up till 4 am, the day of my 7:20 am class. Those were 4 of the most productive hours I’ve had in weeks!

I wish I knew the science to this.

I started off going to bed at 1am and getting up around 8 and then working the usual 15 hour day (2 hours for swimming, eating and God). But, due to the amount of work, someone suggested that I go to bed and get earlier to maximise the morning. So, I started to turn in around 10pm and getting up at 2am ‘ready to attack the day’. In addition, I’d have a 5 minute (no more) around 4pm.

Did it work? Yes – the earlier I went to bed, the earlier I got up, the more productive I was. I actually found that I was more productive, to the extent that daily I was taking a couple of hours less to do the usual amount of work.

It was always amusing when my house mates would arrive home after being in a club/bar and I’d already done a few hours work!
