Thanks Dien.
I think its a better idea to map out your to-do list at the end of the day. Decide what you will do the next day in the last 10 minutes of your day.
So that the first thing you do the next day is dig in and start working.
I try to follow Joe Sugarman's technique - of packing up for the day. Making sure the desk (and the desktop) is clean.
And then make a list of
* What I achieved on that day
* Things to-do the next day
