What the article doesn't mention is to use this effect as a tactic to get going in the morning: Plan your day so that you stop in the middle of an interesting task at the end of the day. I find it's effortless for me to pick it up the next morning.
I used this technique for my lunch break -- with great results. Before I took the break, I was very motivated to finish the project I was working on. But I decided to leave it unfinished. After lunch, I started right back again without 'lost time' checking my email and such.
