I haven't found this. Because I can still see a calendar that shows all the days I hit my goal, my motivation doesn't suddenly evaporate if I miss a day. One of the keys I think is setting goals that you can't fail at. So rather than "go to gym" which is a hard habit to form, you could start with "do 10 pushups". Eventually once the habit has formed you can step it up, but it's far more valuable to win/succeed every day than it is to accomplish lots on one day then laps for 5.

This gives me a tremendous sense of achievement and progress which has been invaluable in the quest to form better habits.
Oh yeah the corner groupings are rad. best thing about the xperia is the keyboard though... I can't stand touch screens!! Although my ideal form factor is candybar the only other phone in existence that does what I need is the Motorola Pro+ which is really fragile. I currently have like 4 xperia sk17a's ... Stockpiling them like a survivalist.
