If it's a work day and I don't wake up on time, I'll pick away at it over the course of the day - usually I'll get a chance to think about it on my tram ride to work and complete it at lunchtime
If it's a weekend I'll just do it at my leisure at some point during the day when I have some time - maybe head to a nice cafe or something.
I'm nowhere near the top 100 - closest has been iirc top 200 a few years back - so it's not like I need to start at 6am.
